A cornerstone of the former is the Pólya--Benz Theorem, classifying a central family of real-root preserving operators on the space of polynomials, as those given by $f(\\partial_z)$ for a Laguerre--Pólya function $f$ and the derivative operator $\\partial_{z}$. We prove that any free (additive) infinitely divisible distribution can be attained as the weak limit of root distributions of Appell polynomials $f_n(\\partial_z)z^n$ as $n\\to\\infty$, for a suitably chosen sequence $f_n$ of Laguerre--Pólya functions.\r\n  Such questions on the (global) limiting distributions of real rooted polynomials belong to the active research area of finite free probability. In contrast to its standard tools, our approach allows for non-compactly supported limiting distributions, (barely) complex rooted polynomials and even provides the full microscopic description of the roots. Moreover, we extend our results to differential operators generating free multiplicative infinitely divisible distributions, to the rectangular free convolution, and to $f_n(\\partial_z)p_n$ for real rooted polynomials $p_n$, implying a generalization of the recent connections between the heat flow and free Brownian motion to any free Lévy process.\r\n  As corollaries, we identify free stable distributions by choosing $f_n$ to be a fixed rescaled Laguerre--Pólya function, and we prove various convergence results on the zero distributions of Jensen polynomials, e.g. the limiting root distribution of Jensen polynomial of the Riemann $Ξ$-function is given by the Cauchy distribution.","lang":"eng"}],"date_created":"2026-08-04T06:07:17Z","external_id":{"arxiv":["2605.31356"]},"department":[{"_id":"94"}],"type":"preprint","author":[{"last_name":"Campbell","first_name":"Andrew","full_name":"Campbell, Andrew"},{"orcid":"0000-0001-9624-2685","last_name":"Jalowy","first_name":"Jonas","full_name":"Jalowy, Jonas","id":"113768"}],"title":"Pólya--Schur problems and free probability","year":"2026","status":"public","date_updated":"2026-08-04T06:07:45Z","_id":"66642","language":[{"iso":"eng"}],"user_id":"113768"},{"intvolume":"       199","date_updated":"2026-08-04T06:07:59Z","publication_status":"published","author":[{"full_name":"Jalowy, Jonas","last_name":"Jalowy","first_name":"Jonas","orcid":"0000-0001-9624-2685","id":"113768"},{"full_name":"Stange, Hanna","first_name":"Hanna","last_name":"Stange"}],"publication_identifier":{"issn":["0304-4149"]},"status":"public","title":"Box-covariances of hyperuniform point processes","year":"2026","volume":199,"doi":"10.1016/j.spa.2026.104996","user_id":"113768","_id":"66641","publisher":"Elsevier BV","language":[{"iso":"eng"}],"article_number":"104996","citation":{"mla":"Jalowy, Jonas, and Hanna Stange. “Box-Covariances of Hyperuniform Point Processes.” <i>Stochastic Processes and Their Applications</i>, vol. 199, 104996, Elsevier BV, 2026, doi:<a href=\"https://doi.org/10.1016/j.spa.2026.104996\">10.1016/j.spa.2026.104996</a>.","ama":"Jalowy J, Stange H.

While designs in regular semilattices go back to Delsarte, our regularity assumptions are weaker than his and need not give rise to an association scheme. In this framework, we extend Mendelsohn's equations, prove a generalized Singleton bound with Steiner systems as equality cases, and determine the block intersection distribution at any block of a Steiner system. In particular, this distribution is independent of the chosen block.\r\n  Specializing to several classical semilattice families, our results recover a number of well-known distributions in coding and design theory. In the Hamming and the $q$-Hamming (or bilinear forms) schemes, they give the local distance distributions of MDS and MRD codes, respectively. In the Johnson and $q$-Johnson (or Graßmann) schemes, they reproduce the block intersection distribution of classical and $q$-analog Steiner systems, equivalently the distance distribution of diameter-perfect constant-weight codes and diameter-perfect constant-dimension subspace codes. For the $q$-Johnson schemes, to the best of our knowledge, this result is new. As a further illustration, we apply our theory to designs of perfect matchings.\r\n  Our approach provides a unified treatment of these cases in the strongest form known in the literature, determining the distribution relative to each individual block or codeword, without averaging and without linearity or additivity assumptions. Moreover, it identifies the natural double-counting objects underlying these distributions, leading to formulas in the regularity parameters of the semilattice and avoiding the more cumbersome expressions that arise in eigenvalue-based approaches via the ambient association scheme."}],"_id":"66731","language":[{"iso":"eng"}],"user_id":"91965","author":[{"last_name":"Kiermaier","first_name":"Michael","full_name":"Kiermaier, Michael"},{"full_name":"Klawuhn, Lukas-André Dominik","last_name":"Klawuhn","orcid":"0009-0009-7736-4885","first_name":"Lukas-André Dominik","id":"91965"}],"year":"2026","title":"Intersection numbers for designs in regular semilattices","status":"public","date_updated":"2026-08-17T10:31:03Z"},{"department":[{"_id":"10"},{"_id":"87"},{"_id":"93"}],"type":"journal_article","date_created":"2024-09-11T22:50:56Z","external_id":{"arxiv":["2407.05444"]},"quality_controlled":"1","citation":{"mla":"Glöckner, Helge, et al. “Boundary Values of Diffeomorphisms of Simple Polytopes, and Controllability.” <i>Differential Geometry and Its Applications</i>, vol. 104, 102404, 2026, doi:<a href=\"https://doi.org/10.1016/j.difgeo.2026.102404\">10.1016/j.difgeo.2026.102404</a>.","bibtex":"@article{Glöckner_Grong_Schmeding_2026, title={Boundary values of diffeomorphisms of simple polytopes, and controllability}, volume={104}, DOI={<a href=\"https://doi.org/10.1016/j.difgeo.2026.102404\">10.1016/j.difgeo.2026.102404</a>}, number={102404}, journal={Differential Geometry and its Applications}, author={Glöckner, Helge and Grong, Erlend and Schmeding, Alexander}, year={2026} }","ama":"Glöckner H, Grong E, Schmeding A.

Drawing on a dialogic feedback framework, the study analyzes students’ feedback processes in an ecologically valid learning context. Grounded in a sociocultural perspective, the framework integrates Carless’ dialogic conceptualization of feedback, Shute’s feedback typology, and Vergnaud’s scheme theory. Eight eighth-graders from a German secondary school worked individually on percentage problems at home, video-recorded via online conferencing. Data included screen recordings and think-aloud protocols, which were analyzed using qualitative text analysis. Results reveal large individual differences in feedback processes—students vary in when and how they access feedback messages and how they make sense of them. Successfully solving a task after feedback does not always indicate understanding; in some cases, feedback aided procedural completion without conceptual insight. The effectiveness depended on the alignment between task design, feedback message content, and students’ actual difficulties. The study concludes that qualitative analysis of feedback processes with digital technologies in ecologically valid settings is necessary to target specific student difficulties and promote learning.</jats:p>","lang":"eng"}],"date_created":"2026-08-24T14:17:44Z","department":[{"_id":"360"}],"type":"journal_article"},{"intvolume":"       288","date_updated":"2024-09-25T08:18:44Z","author":[{"id":"49178","first_name":"Tobias","last_name":"Weich","orcid":"0000-0002-9648-6919","full_name":"Weich, Tobias"},{"last_name":"Budde","first_name":"Julia","full_name":"Budde, Julia"}],"title":"Wave Front Sets of Nilpotent Lie Group Representations","year":"2025","doi":" https://doi.org/10.1016/j.jfa.2024.110684","language":[{"iso":"eng"}],"issue":"1","publication":"Journal of Functional Analysis","department":[{"_id":"10"},{"_id":"623"},{"_id":"548"}],"type":"journal_article","date_created":"2022-06-22T09:56:43Z","file":[{"access_level":"open_access","file_size":978990,"file_name":"2103.02968.pdf","date_updated":"2022-06-22T09:56:39Z","relation":"main_file","content_type":"application/pdf","file_id":"32100","creator":"weich","date_created":"2022-06-22T09:56:39Z"}],"has_accepted_license":"1","status":"public","volume":288,"ddc":["510"],"user_id":"49178","_id":"32099","project":[{"name":"TRR 358 - B02: TRR 358 - Spektraltheorie in höherem Rang und unendlichem Volumen (Teilprojekt B02)","_id":"356","grant_number":"491392403"},{"grant_number":"422642921","_id":"355","name":"Mikrolokale Methoden für hyperbolische Dynamiken"}],"citation":{"mla":"Weich, Tobias, and Julia Budde. “Wave Front Sets of Nilpotent Lie Group Representations.” <i>Journal of Functional Analysis</i>, vol. 288, no. 1, 2025, doi:<a href=\"https://doi.org/ https://doi.org/10.1016/j.jfa.2024.110684\"> https://doi.org/10.1016/j.jfa.2024.110684</a>.","bibtex":"@article{Weich_Budde_2025, title={Wave Front Sets of Nilpotent Lie Group Representations}, volume={288}, DOI={<a href=\"https://doi.org/ https://doi.org/10.1016/j.jfa.2024.110684\"> https://doi.org/10.1016/j.jfa.2024.110684</a>}, number={1}, journal={Journal of Functional Analysis}, author={Weich, Tobias and Budde, Julia}, year={2025} }","ama":"Weich T, Budde J.

For that, we first review the literature related to students’ selection and use of resources in mathematics education in different pedagogical settings (presentation 1). Second, we develop insights from the different studies that participate in this symposium (presentation 2–6), at school as well as at university level. Results show that attempts have been made to provide students opportunities to develop agency of their mathematics learning, in particular with the development and provision of numerous digital tools and learning resources at university level and related to innovative pedagogical approaches. At the same time, it is not obvious how these tools and resources help students to develop deeper conceptual understandings. Certainly, students often ‘demand’ more student-centered and autonomous education approaches (e.g., at university level), also in mathematics education. Further, it seems that authentic problem-based education approaches are more motivating for students. These ‘innovative’ approaches necessitate particular types of structure and support for students. Moreover, they require different ways of providing resources that students can and want to interact with, and that help students to navigate through the curriculum to develop their own learning paths. At the same time, teachers also need support on how to orchestrate student learning with the available resources in such environments, so to be able to attend to students’ individual needs.

It may be beneficial to introduce machine learning, such as decision trees (DTs), at an early stage of education. The data-based construction of DTs is an example of a machine learning process, which can be addressed in mathematics or statistics teaching because of relatively low prior knowledge requirements. This paper focuses on investigating how sixth-grade students create and evaluate data-based DTs. The basis is a teaching unit that aims to lay the foundation for machine learning and enhance students’ understanding of the process. We investigate students’ processes in detail while they build DTs with data cards about food items to predict whether a new item is recommendable. After the teaching unit, an interview study examines students’ strategies for creating decision trees. The findings contribute to understanding students’ learning processes and the challenges when working with decision trees.</jats:p>","lang":"eng"}],"publication":"ZDM – Mathematics Education","citation":{"bibtex":"@article{Podworny_Biehler_Fleischer_2025, title={Young students’ engagement with data to create decision trees}, DOI={<a href=\"https://doi.org/10.1007/s11858-024-01649-w\">10.1007/s11858-024-01649-w</a>}, journal={ZDM – Mathematics Education}, publisher={Springer Science and Business Media LLC}, author={Podworny, Susanne and Biehler, Rolf and Fleischer, Yannik}, year={2025} }","ama":"Podworny S, Biehler R, Fleischer Y.

We conceptualized data-based decision tree construction using nine key aspects that we intended to teach, tested variations of two design elements in teaching, and analyzed the interviews qualitatively to compare student behavior to intended outcomes. We found high alignment to intentions but also deviations in data activities and informal or context-based rather than data-based reasoning. The design element of context-free (blinded) data seems to enhance data-based reasoning, while the design element of data card use showed diagnostic potential.</jats:p>","lang":"eng"}],"publication":"ZDM – Mathematics Education","issue":"1","type":"journal_article","department":[{"_id":"363"}],"date_created":"2025-04-22T07:59:07Z","publication_status":"published","date_updated":"2025-04-22T08:00:59Z","intvolume":"        57","title":"Exploring students’ constructions of data-based decision trees after an introductory teaching unit on machine learning","year":"2025","author":[{"id":"42660","last_name":"Fleischer","orcid":"https://orcid.org/0000-0003-0318-0329","first_name":"Yannik","full_name":"Fleischer, Yannik"},{"full_name":"Biehler, Rolf","first_name":"Rolf","last_name":"Biehler","id":"16274"}],"publication_identifier":{"issn":["1863-9690","1863-9704"]},"doi":"10.1007/s11858-025-01663-6","main_file_link":[{"url":"https://link.springer.com/article/10.1007/s11858-025-01663-6"}],"language":[{"iso":"eng"}]},{"_id":"59664","language":[{"iso":"eng"}],"user_id":"113768","year":"2025","title":"Zeros and exponential profiles of polynomials I: Limit distributions,  finite free convolutions and repeated differentiation","status":"public","author":[{"id":"113768","first_name":"Jonas","last_name":"Jalowy","orcid":"0000-0001-9624-2685","full_name":"Jalowy, Jonas"},{"first_name":"Zakhar","last_name":"Kabluchko","full_name":"Kabluchko, Zakhar"},{"first_name":"Alexander","last_name":"Marynych","full_name":"Marynych, Alexander"}],"date_updated":"2025-04-23T14:38:04Z","external_id":{"arxiv":["2504.11593"]},"date_created":"2025-04-23T14:37:41Z","type":"preprint","department":[{"_id":"94"}],"publication":"arXiv:2504.11593","citation":{"mla":"Jalowy, Jonas, et al. “Zeros and Exponential Profiles of Polynomials I: Limit Distributions,  Finite Free Convolutions and Repeated Differentiation.” <i>ArXiv:2504.11593</i>, 2025.","bibtex":"@article{Jalowy_Kabluchko_Marynych_2025, title={Zeros and exponential profiles of polynomials I: Limit distributions,  finite free convolutions and repeated differentiation}, journal={arXiv:2504.11593}, author={Jalowy, Jonas and Kabluchko, Zakhar and Marynych, Alexander}, year={2025} }","ama":"Jalowy J, Kabluchko Z, Marynych A.

The method is based on establishing an\r\nequivalence between the existence of a limiting empirical zero distribution\r\n$\\mu$ and the existence of an exponential profile $g$ associated with the\r\ncoefficients of the polynomials $(P_n)_{n \\in \\mathbb{N}}$. The exponential\r\nprofile $g$, which can be roughly described by $[z^k]P_n(z) \\approx \\exp(n\r\ng(k/n))$, offers a direct route to computing the Cauchy transform $G$ of $\\mu$:\r\nthe functions $t \\mapsto tG(t)$ and $\\alpha \\mapsto \\exp(-g'(\\alpha))$ are\r\nmutual inverses. This relationship, in various forms, has previously appeared\r\nin the literature, most notably in the paper [Van Assche, Fano and Ortolani,\r\nSIAM J. Math. Anal., 1987].\r\n  As a first contribution, we present a self-contained probabilistic proof of\r\nthis equivalence by representing the polynomials as generating functions of\r\nsums of independent Bernoulli random variables. This probabilistic framework\r\nnaturally lends itself to tools from large deviation theory, such as the\r\nexponential change of measure. The resulting theorems generalize and unify a\r\nrange of previously known results, which were traditionally established through\r\nanalytic or combinatorial methods.\r\n  Secondly, using the profile-based approach, we investigate how the\r\nexponential profile and the limiting zero distribution behave under certain\r\noperations on polynomials, including finite free convolutions, Hadamard\r\nproducts, and repeated differentiation. In particular, our approach yields new\r\nproofs of the convergence results `$\\boxplus_n \\to \\boxplus$' and `$\\boxtimes_n\r\n\\to \\boxtimes$', extending them to cases where the distributions are not\r\nnecessarily compactly supported.","lang":"eng"}]}]
