She has found an "ideal research environment" at the University of Münster, in mathematics in general and in her research group for arithmetic geometry. "The prize makes these good conditions even more perfect."

"Awareness and recognition for FAIR data culture must be increased." says Mario Ohlberger, Mathematics Münster's spokesperson, in the "Making MaRDI" interview, a series of the Mathematical Research Data Initiative. To learn about his role in establishing a FAIR culture for mathematical research data, read this interesting interview.

The journal "Inventiones mathematicae" is considered a top journal in the mathematical community. This year, the journal published a paper by postdoc Dr. Konstantinos Zemas and his PhD supervisor Prof. Dr. Stephan Luckhaus (University of Leipzig). In this interview, Konstantinos talks about the content of the paper, and how the topic and his research have developed since the publication.

Dr. Anna Duwenig, Prof. Dr. Astrid an Huef, Prof. Dr. Maria Grazia Viola, Dr. Magdalena Georgescu, and Prof. Dr. Kristin Courtney have met last week in Münster to work on regularity conditions on a groupoid which can guarantee finite noncommutative covering dimension on its corresponding C*-algebra.

The ICM 2022 was reorganised as an online event, and this event hosted some of the talks real life. The focus of the event in Copenhagen, supported by Mathematics Münster, was the Geometry and Topology sections. Similar events were organized at other locations from 6–14 July 2022. Video recordings of all talks are now availabe at the YouTube channel of the International Mathematical Union.

Dr. Giles Gardam, postdoc at Mathematics Münster, convinced the German Research Foundation (DFG) with his project: The DFG is providing funding from the Emmy Noether Programme of just over one million euros for the mathematician. This means that he can build up his own research group at the Mathematical Institute in the coming six years. The aim of the Emmy Noether Programme is to offer outstanding junior researchers scientific independence and qualify them for a university professorship.

A year ago, Prof. Ralf Schindler and Prof. David Asperó published a proof uniting two hitherto competing assumptions in set theory. The result is considered a milestone in research in the field of infinities, one of the theoretical foundations of mathematics. A portrait of Ralf Schindler has now been published in Münster University's newspaper.

Artificial intelligence has long been part of our everyday lives. In the current issue of the university newspaper "wissen I leben", scientists from various fields shed light on the potential and problems that AI brings with it. Research projects by Mathematics Münster's researchers are also part of the focus topic. [de, page 4]

Recently, the new journal "Model Theory" was launched and is now welcoming submissions. It is published by the nonprofit Mathematical Sciences Publishers (MSP). The editors-in-chief are Prof. Dr. Martin Hils from Mathematics Münster and Prof. Rahim Moosa (University of Waterloo).

In May David Asperó and Ralf Schindler published their proof on a question from the 1990s about the relationship of two prominent axioms of set theory which both decide how many real numbers there are. Now Natalie Wolchover reports for the Quanta Magazine on the proof, its relevance and history.

Postdoc Dr. Giles Gardam, postdoc at Mathematics Münster, has recently disproved an 80 year old algebra conjecture. Now Erica Klarreich, a renowned science journalist, has reported on his counterexample and its great significance for the research area.

The Kaplansky conjectures are three long-standing open problems on the group rings of torsion-free groups. Last week, Dr. Giles Gardam, postdoc in Mathematics Münster's topology group, announced that he succeeded to disprove the strongest of these three conjectures, namely the unit conjecture. In this interview, he tells us what fascinates him about the conjecture, how he came to his findings, and how the research community reacted. 

Prof. Dr. Erez Raz, a cell biologist, and Prof. Dr. Angela Stevens, a mathematician, aim to further strengthen and deepen the exchange between experimental biology and mathematics in their new project "Cell Dynamics and Mathematical Modelling". It is one of eleven "Topical Programs" that have recently been funded by the University of Münster.

In the research project “inSight – Multiscale imaging of organ-specific inflammation” that receives approximately ten million euros in funding, scientists focus on the question of how the body regulates inflammation in different organs and, to this end, develop a specific imaging methodology. Prof. Dr. Benedikt Wirth, investigator of Mathematics Münster, is involved as principal investigator.

The PhD thesis of Dr. Barbara Verfürth from the Institute of Analysis and Numerics demonstrates pioneering mathematical work by making her the first person to calculate the connection between materials and their refraction. This fundamental work in the field of mathematics can help later in developing high-resolution microscopes – or in improving sound-absorbing walls, which are important for good acoustics in concert halls or recording studios.

Hours of contemplation, approaching a solution in small steps, and a healthy scepticism towards computer-generated results. In these guest articles, two mathematicians at the University of Münster, Dr. Franziska Jahnke und Dr. Mira Schedensack, explain what mathematical research means to them and what the aim of this research is. Both undertake research and teaching at the University of Münster within the framework of the MATHRIX junior professorships, which were established in 2017 to promote gender equality in mathematics.

After ten years, Prof. Raimar Wulkenhaar from the University of Münster’s Mathematical Institute and his colleague Dr. Erik Panzer from the University of Oxford have solved a mathematical equation which was considered to be unsolvable. The equation is to be used to find answers to questions posed by elementary particle physics. In this interview with Christina Heimken, Wulkenhaar looks back on the challenges encountered in looking for the formula for a solution and he explains why the work is not yet finished.
