The article "Issue 32(1)" in the Communications of the German Mathematical Society (DMV) covers various topics such as the DMV Student Conference 2024 in Ilmenau, the significance of mathematics in museums, job opportunities for mathematics graduates, and the name of the DMV. The president of the DMV emphasizes the need to attract more and younger members and to make greater efforts towards women and diversity. It also reports on the discussion about renaming the DMV, for which suggestions from members are being collected. The 2023 PISA study shows that the average mathematical and reading competencies of adolescents in many OECD countries have declined compared to the previous study in 2018. Scientific competence has also decreased. In Germany, the performance losses in all three areas are above average. The reasons for the deterioration are mainly attributed to the effects of the COVID-19 pandemic, as well as language difficulties, interest, and motivation. The exhibition "From Newton to Einstein - a journey through space and time" was developed at the Max Planck Institute for Gravitational Physics in Potsdam and is now on display in Tübingen. The award winner Carla Cederbaum has also developed other projects, such as a book on mathematical magic tricks and the publication series "Oberwolfach-Snapshots of Modern Mathematics". Mathematicians Carolin Mehlmann and Thomas Richter from the University of Magdeburg participated in an expedition of the Polarstern to the Arctic Ocean to calibrate a new hybrid sea ice model. The hybrid sea ice model combines particle and continuum methods to better resolve the different sea ice regimes on different local scales. The text deals with the deformation theorem in differential geometry. It is shown that a manifold with boundary possesses a metric with certain properties if the double of the manifold carries such a metric. The question of whether the converse of this statement holds is also raised. The text deals with hypothesis testing and the problem of multiple error probability. Various methods for solving this problem are presented, including the Bonferroni correction and the development of better methods taking into account the dependency structure of the tests. It also addresses pseudoline arrangements, which have connections to combinatorics, geometry, and computer science. The text deals with various mathematical topics, including sorting networks, pseudoline arrangements, Rubik's cube, the PISA study, calculating machines, student studies, Felix Klein, and international cooperation in mathematics. Various concepts and applications are explained, such as the creation of sorting networks from pseudoline arrangements, the use of Markov chains to generate random pseudoline arrangements, and the development of calculation aids and calculating machines. The importance of student studies and international cooperation in mathematics is also emphasized. The text provides an insight into various mathematical topics and their applications. The article reports on Renate Tobies, a visiting scientist at Friedrich Schiller University Jena. She studied chemistry and mathematics and obtained her habilitation in the history of mathematics and natural sciences. Tobies has taught in various German cities and in Austria and was the managing editor of NTM History and Ethics of Natural Sciences, Technology, and Medicine. The article deals with a position paper by the professional societies DMV. [Extracted from the article]

The article "President's Greeting" reports on the position paper on equal opportunities and diversity of the German Mathematical Society (DMV). The DMV presidency emphasizes the importance of a diverse, respectful, and inclusive community. It is mentioned that the discussion about a possible renaming of the DMV has resurfaced, but no name change has taken place so far. The presidency has established a specialist group for gender, diversity, and sustainability in mathematics and proposes a participatory process to shape the discussion about the name of the DMV. Furthermore, reference is made to a paper adopted by various mathematical and scientific societies, condemning antidemocratic and nationalist approaches in Germany. It is emphasized that science requires openness, international cooperation, democracy, and the rule of law. [Extracted from the article]

The article delves into the Ellsberg paradox, showcasing its significance in economic and social decision-making theories, specifically addressing the ambiguity in probability assessment. It highlights Daniel Ellsberg's discovery, his renowned release of the Pentagon Papers and his pioneering work on decision theory. It states that the paradox challenges the independence of irrelevant alternatives axiom, revealing how individuals' choices contradict their subjective beliefs about probabilities.

The issue of the "Mitteilungen der DMV" (Announcements of the German Mathematical Society) from March 1, 2023, contains various articles on mathematical topics. One article by Jessica Wynne deals with the beauty of mathematical chalkboard images. The president of the DMV, Joachim Escher, gives a greeting. Other articles discuss topics such as the Tilings Encyclopedia, the development of ChatGPT in AI research, and mathematics in the digital society. There is also an article on the geometry of negotiation tables and a contribution on life and work in Germany from an external perspective. The position paper by DMV, GDM, and MNU on combating the shortage of mathematics teachers is also presented. The issue concludes with information about new members, appointments, promotions, and the imprint. [Extracted from the article]

The article offers briefs related to Deutsche Mathematiker-Vereinigung (DMV). Topics include Science Council published the position paper impetus from the Covid- 19 crisis for further development of the science system in Germany passed to reorientation of science policy; and response capability in policy advice about a lack of sovereignty and Security in the digital space up to strategic challenges in internationalization.

The article informs about case study of a serious and multiple ethical misconduct after an author submitted a paper to five journals for publication and committed some form of plagiarism. Topics include mathematics and in sciences in general, multiple submissions of the same results or parallel papers are prohibited as serious ethical misconduct; and mathematics simultaneous or concurrent submission of a manuscript describing the same research publication in the electronic online systems.
