Within this framework, we present a model of meaning for the concepts of total differentiability and total derivative that provides a variety of possible interpretations and aspects. We then use the proposed model of meaning as a tool for analyzing three different textbooks for mathematics majors on the topic of multidimensional differentiability. Our paper is an example of a subject matter analysis of a topic in university mathematics carried out in a structured way. The model of meaning for total differentiability presented in this paper could inspire course design and analysis including the design of assignments and assessments for students. Moreover, it could serve as a valuable research tool for further analyses. For example, it could be used as a framework for analyzing courses taught or as a basis for developing a test instrument to assess students’ understanding. With our textbook analysis, we begin to examine the landscape of textbooks regarding differentiability concepts in the multidimensional case, shedding light on the diversity of meaning facets that are covered in the textbooks. These results could be useful for guiding instructors and learners in selecting and using textbooks for teaching and learning based on their respective needs.</jats:p>","lang":"eng"}],"_id":"54144","language":[{"iso":"eng"}],"publisher":"Springer Science and Business Media LLC","doi":"10.1007/s11858-024-01584-w","user_id":"37888","author":[{"first_name":"Elisa","last_name":"Lankeit","full_name":"Lankeit, Elisa"},{"full_name":"Biehler, Rolf","first_name":"Rolf","last_name":"Biehler","id":"16274"}],"publication_identifier":{"issn":["1863-9690","1863-9704"]},"status":"public","title":"The meaning landscape of the concept of the total derivative in multivariable real analysis textbooks: an analysis based on a new model of meaning","year":"2024","date_updated":"2024-05-10T07:49:19Z","publication_status":"published"},{"type":"journal_article","department":[{"_id":"100"}],"date_created":"2024-04-17T12:26:51Z","abstract":[{"lang":"eng","text":"It is known that the notion of a transitive subgroup of a permutation group\r\n$G$ extends naturally to subsets of $G$.

We prove existence of solutions to this system in finite dimensions and further prove that its bounded solutions converge weakly to weakly Pareto optimal points. In addition, we obtain a convergence rate of order \\(\\mathcal{O}(t^{-2})\\) for the function values measured with a merit function. This approach presents a good basis for the development of fast gradient methods for multiobjective optimization.","lang":"eng"}],"publication":"SIAM Journal on Optimization","issue":"3","department":[{"_id":"101"},{"_id":"655"}],"type":"journal_article","keyword":["multiobjective optimization","Pareto optimization","Lyapunov analysis","gradient-likedynamical systems","inertial dynamics","asymptotic vanishing damping","fast convergence"],"date_created":"2022-07-28T11:53:02Z","article_type":"original","intvolume":"        34","publication_status":"published","date_updated":"2024-07-02T09:27:39Z","publication_identifier":{"issn":["1095-7189"]},"author":[{"orcid":"https://orcid.org/0000-0003-3384-3496","first_name":"Konstantin","last_name":"Sonntag","full_name":"Sonntag, Konstantin","id":"56399"},{"full_name":"Peitz, Sebastian","first_name":"Sebastian","last_name":"Peitz","orcid":"0000-0002-3389-793X","id":"47427"}],"year":"2024","title":"Fast Convergence of Inertial Multiobjective Gradient-Like Systems with Asymptotic Vanishing Damping","doi":"10.1137/23M1588512","language":[{"iso":"eng"}],"citation":{"ieee":"K.

The method is based on the data-based identification of a discrete Lagrangian density. It is a geometric machine learning technique in the sense that the variational structure of the true field theory is reflected in the data-driven model by design. We provide a rigorous convergence statement of the method. The proof circumvents challenges posed by the ambiguity of discrete Lagrangian densities in the inverse problem of variational calculus.\r\nMoreover, our method can be used to quantify model uncertainty in the equations of motions and any linear observable of the discrete field theory.

By this, we mean tasks that are situated by typical everyday challenges of mathematics teaching and in which PSTs must use their mathematical knowledge and skills in a professionally relevant way. In this paper, we analyze answers that PSTs have created to an interface task on symmetry. The PSTs were asked to clarify a student’s question from a mathematical perspective and then give a suitable elementarized answer. We situate these two steps theoretically and reconstruct the mathematical reasoning in PSTs' answers. Through qualitative content analysis, we examined how PSTs justify figures' symmetries from a university mathematics perspective and when responding to the fictitious student. The scenario of a student questioning the existence of 100° rotationally symmetrical figures elicited rich and varied responses, proving suitable for an interface task. We compared PSTs' reasoning related to mathematical clarification with the reasoning related to elementarization. In many cases, this revealed a productive use of course content. An interesting result is that there is no uniform picture as to whether the arguments are more detailed in the mathematical clarification or in the elementarization.</jats:p>"}],"publication":"ZDM – Mathematics Education","doi":"10.1007/s11858-024-01633-4","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://link.springer.com/content/pdf/10.1007/s11858-024-01633-4.pdf"}],"article_type":"original","date_updated":"2024-09-04T09:33:45Z","publication_status":"published","publication_identifier":{"issn":["1863-9690","1863-9704"]},"author":[{"last_name":"Hoffmann","first_name":"Max","orcid":"0000-0002-6964-7123","full_name":"Hoffmann, Max","id":"32202"},{"id":"16274","full_name":"Biehler, Rolf","last_name":"Biehler","first_name":"Rolf"}],"year":"2024","title":"Using academic mathematical knowledge when working on interface tasks–analyses of pre-service teachers’ arguments about rotationally symmetric figures","oa":"1","quality_controlled":"1","citation":{"bibtex":"@article{Hoffmann_Biehler_2024, title={Using academic mathematical knowledge when working on interface tasks–analyses of pre-service teachers’ arguments about rotationally symmetric figures}, DOI={<a href=\"https://doi.org/10.1007/s11858-024-01633-4\">10.1007/s11858-024-01633-4</a>}, journal={ZDM – Mathematics Education}, publisher={Springer Science and Business Media LLC}, author={Hoffmann, Max and Biehler, Rolf}, year={2024} }","ama":"Hoffmann M, Biehler R.
