Starting from the Krotov framework, we reformulate the forward and backward propagation steps using Cayley-type schemes that preserve unitarity and symmetry at the discrete level. This approach eliminates the need for matrix exponentials and commutators, leading to significant computational savings while maintaining higher-order accuracy. We first recall the standard linear setting and then extend the formulation to nonlinear Schrödinger and Gross-Pitaevskii equations using a Cayley-polynomial interpolation strategy. Numerical experiments on state-transfer problems illustrate that the CF-Cayley method achieves the same accuracy as high-order exponential or Cayley-Magnus schemes at substantially lower cost, especially for longtime or highly oscillatory dynamics. In the nonlinear regime, the structure-preserving properties of the method ensure stability and norm conservation, making it a robust tool for large-scale quantum control simulations. The proposed framework thus bridges geometric integration and optimal control, offering an efficient and reliable alternative to existing exponential-based propagators.","lang":"eng"}],"citation":{"mla":"Wembe Moafo, Boris Edgar, et al. <i>Cayley Commutator-Free Methods for Krotov-Type Algorithms in Quantum Optimal Control</i>. 2026, doi:<a href=\"https://doi.org/10.48550/ARXIV.2603.11697\">10.48550/ARXIV.2603.11697</a>.","bibtex":"@inproceedings{Wembe Moafo_Ali_Meier_Ober-Blöbaum_2026, title={Cayley Commutator-free Methods for Krotov-Type Algorithms in Quantum Optimal Control}, DOI={<a href=\"https://doi.org/10.48550/ARXIV.2603.11697\">10.48550/ARXIV.2603.11697</a>}, author={Wembe Moafo, Boris Edgar and Ali, Usman and Meier, Torsten and Ober-Blöbaum, Sina}, year={2026} }","ama":"Wembe Moafo BE, Ali U, Meier T, Ober-Blöbaum S.

In this paper we establish an exponential trim turnpike property for a class of optimal control problems with structural properties related to Abelian Lie group symmetries. The key ingredient of our approach is the introduction of an appropriate reduced optimal control problem. We show that extremals of the original problem can be characterized through a reduced Hamiltonian boundary value problem that coincides with the optimality system of the reduced problem. Under a hyperbolicity assumption on the equilibrium of the corresponding reduced Hamiltonian system we prove that optimal trajectories remain exponentially close, up to boundary layers near the endpoints, to a trim primitive defined by the static reduced problem.

To this end, we developed a heuristic training that\r\nintroduced strategy keys (heuristic aid cards) accompanied by explanatory videos. By\r\nleveraging variations in the successful application of the heuristics between students\r\nand across multiple sessions (73 students in 4 training situations and 3 problems\r\nin a final test), we discover from regression models with student and task-fixed effects\r\nthat a successful use of heuristics (i.e., an heuristic occurred, that heuristic had\r\na high suitability regarding the problem, and it was applied correctly) leads to more\r\nsuccessful mathematical problem solving. Regarding the underlying mechanism, we\r\nfind that all dimensions of heuristic use (occurrence, suitability, and application\r\nof heuristics) are positively related to problem-solving success. When comparing\r\nthe predictive capacity of all three aspects, we identified the correct application of\r\nheuristics as particularly conducive for better problem-solving success. In comparing\r\nthe group of students with high to those with low initial math competence, we find no significant differences in the relationship between heuristic use and problemsolving\r\nsuccess across achievement groups.

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":"2026-08-04T06:06:09Z","department":[{"_id":"94"}],"type":"journal_article","citation":{"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.","lang":"eng"}]},{"date_updated":"2026-07-01T15:02:58Z","intvolume":"       104","article_type":"original","status":"public","title":"Boundary values of diffeomorphisms of simple polytopes, and controllability","year":"2026","author":[{"full_name":"Glöckner, Helge","first_name":"Helge","last_name":"Glöckner","id":"178"},{"full_name":"Grong, Erlend","last_name":"Grong","first_name":"Erlend"},{"last_name":"Schmeding","first_name":"Alexander","full_name":"Schmeding, Alexander"}],"doi":"10.1016/j.difgeo.2026.102404","user_id":"178","volume":104,"article_number":"102404","language":[{"iso":"eng"}],"_id":"56116","quality_controlled":"1","publication":"Differential Geometry and its Applications","citation":{"ama":"Glöckner H, Grong E, Schmeding A.

Es ist für die Präsenzlehre konzipiert und unterstützt Lehrende dabei, den Übergang von der individuellen Auseinandersetzung mit wissenschaftlichen Texten hin zu einer kollaborativ-sozialen Aushandlung des Gelesenen in Lehrveranstaltungen zu organisieren und zu strukturieren. Im Beitrag wird das digitale kollaborative Tool AnnoPy vorgestellt und gezeigt, welche Potenziale sich für die Analyse von Daten über Lernende durch die Integration von KI-basierter Learning Analytics in das Tool ergeben. Anhand von exemplarischen Daten aus einer Vorlesung der Mathematikdidaktik wird zunächst vorgestellt, wie in AnnoPy eine algorithmisch-händische Analyse und Datenauswertung erfolgte, um dann diese Art der Auswertung mit einer KI-gestützten Auswertung, bei der ein MCP-Server eingebunden wurde, zu vergleichen."}],"language":[{"iso":"ger"}],"main_file_link":[{"open_access":"1","url":"https://www.transcript-verlag.de/978-3-8376-8045-4/learning-analytics-artificial-intelligence-und-data-mining-in-der-hochschulbildung/?number=978-3-8394-5876-1"}],"doi":"10.14361/9783839458761","author":[{"id":"15099","first_name":"Oliver","last_name":"Scholle","full_name":"Scholle, Oliver"},{"full_name":"Rezat, Sara","first_name":"Sara","last_name":"Rezat","id":"58338"},{"id":"31132","full_name":"Rezat, Sebastian","last_name":"Rezat","first_name":"Sebastian"},{"full_name":"Niehus, Dominik","first_name":"Dominik","last_name":"Niehus"}],"publication_identifier":{"isbn":["978-3-8376-8045-4"]},"year":"2026","title":"AnnoPy – Potenziale von KI-basierter Learning Analytics für die Förderung wissenschaftlicher Textkompetenz","publication_status":"published","date_updated":"2026-08-25T07:09:44Z"}]
