International Day of Women in Mathematics 2023

At the CRC Colloquium, a large audience of both CRC members and guests enjoyed three informative talks and engaged with the speakers.

The theatre performance afterwards "Diving into Math with Emmy Noether", hosted at ZIB, attracted an even larger audience. The play, written by Sandra Schüddekopf and Anita Zieher in cooperation with the historians Mechthild Koreuber (former women's representative of FU) and David E. Rowe, was was first performed at Freie Universität in 2019 and returned this year in it's English version.

The reception afterwards gave the audience opportunity to reflect on the day's various inputs.

14:00h (s.t.): Special CRC 1114 Colloquium, Arnimallee 3, lecture hall

Welcome address by Prof. Dr. Günter M. Ziegler

With talks from and about women in Mathematics. 

14:00h: Dr. Agnes Lamacz-Keymling (TU Dortmund):
Sound absorption by perforated walls

Asymptotic analysis of periodic multiscale models became possible with the development of the method of homogenization in the 1970s.If the periodicity length is small compared to the size of the sample of the medium it turns out that the original equation with periodic coefficients is approximated well by an effective model with constant coefficients.

In this talk our interest lies in the mathematical analysis of a sound absorbing perforated plate, e.g. along the wall or ceiling of a room. To this end we analyze the Helmholtz equation in a complex domain where a sound absorbing structure is modelled by a periodic geometry with periodicity $\varepsilon>0$. A resonator volume of thickness $\varepsilon$ is connected with thin channels (opening $\varepsilon^3$) with the main part of the macroscopic domain. We analyze solutions in the limit $\varepsilon\to 0$ to find that while the lowest order approximation is trivial the effective system at order $\varepsilon$ indeed describes sound absorption.

The talk is based on a joint work with Patrizia Donato and Ben Schweizer.

ca. 15:30h: Dr. Anna Ransiek (FU Berlin):
Why is math still a man’s world? Possible explanations from an excellent mathematical research environment.

The persistence of gender disparities in mathematics in German science and academia can still be observed. Moreover, the proportion of female scientists decreases continuously from one career level to the next, all the way to top positions in science/academia. Gatekeeping is assumed as one reason for the maintenance of this phenomena. Gatekeepers influence access to and advancement in the science system. They recruit researchers or they provide support in form of knowledge relevant for career advancement and open the way for further career steps.

The results introduced in the presentation are based on 44 qualitative semi-structured interviews with scientific gatekeepers in leadership positions in a mathematical cluster of excellence in Germany. The presentation will highlight ways of thinking and acting on side of the gatekeepers that may create (possible) barriers for female PhDs and Postdocs in an excellent mathematical research environment.

ca. 16:00h: Dr. des. Esto Mader & Dr. Nelly Mouawad (FU Berlin, MINToring):
Participating in girls‘ outreach activities: benefits for faculty

Looking for brilliant junior staff? Outreach addresses audience outside of academia, but it is a two way street. Addressing girls who are interested in mathematic can encourage them to dare a leap into science. Furthermore, it brings benefits for faculty stuff like the development of teaching skills, networking within the faculty, learning ways to communicate complex contents for a wider audience and so on. We will present one example of girls’ outreach at FU, the MINToring program, to show a variety of benefits for scientists.

16:30h: Diving into Math with Emmy Noether — A theatre performance by Portraittheater Vienna.
ZIB, lecture hall

CRC1114 proudly presents a special performance about the life of one of history‘s most influential mathematicians—who happened to be female. Afterwards, please stay for a small bite, drinks and discussions. The performance will be in English.

The performance is explicitely open to anyone interested to attend: Bring your family, students, colleagues!

12:00h (s.t.): Kovalevskaya Lunch with Anja Schloemerkemper

Female PhD-students of CRC1114, BMS and MATH+ are invited to get to know Prof. Dr. Anja Schlömerkemper, mathematician and vice president equal opportunity & career planning at Universität Würzburg.

Application required: diversity@mathplus.de

14:15h: Special MATH+/BMS Kovalevskaya Lecture
Takustr. 9, lecture hall. Tea & Cookies start at 13:00h.

Anja Schlömerkemper (Uni Würzburg):
Various Structures in Mathematics of Materials

In many materials, interesting structures can be observed on various scales. Modeling and investigation of their properties results in challenging mathematical problems, which involve for instance minimization of variational problems, solutions of evolutionary equations or limit passages in homogenization problems. In this talk, an introduction to these topics and an overview of some related recent results will be provided.
Anja Schlömerkemper has been a professor of Mathematics at the University of Würzburg since 2011. She works in mathematical analysis with applications to materials science and physics. In particular, she investigates elastic and magnetic materials by involving methods from the calculus of variations, the theory of partial differential equations and homogenization theory. She was trained as a physicist in Göttingen,
obtained her PhD in Mathematics in 2002 at Leipzig University and spent time at the Universities of Oxford and Stuttgart, at the Max Planck Institute for Mathematics in the Sciences in Leipzig and at the Universities of Erlangen-Nuremberg and Bonn.
The Kovalevskaya Colloquium has been a MATH+/BMS tradition since 2006. This event will be its 30th edition.
