Description and practical details

We are pleased to announce the EMS Women in Mathematics Day 2025

The Women in Math Committee (WiM) of the European Mathematical Society is organising an event called "EMS/WiM Day" within the initiative of "May 12th", a celebration of women in Mathematics in memory of Maryam Mirzakhani. The event consists of scientific talks (at the level of a Colloquium talk) of two distinguished speakers, which will take place online on Friday, May 9th, 2025, with the following schedule:

 15:00 Welcome

 15:15 Maria Colombo (EPF Lausanne)

 16:15 Özlem Imamoglu (ETH Zurich)

 Any interested person may attend at:

 TITLES AND ABSTRACTS

 Speaker: Maria Colombo (EPF Lausanne)

 Title: Instability and nonuniqueness in fluid equations

 Abstract: For the two dimensional Euler equations, a classical result by Yudovich states that solutions are unique in the class of bounded vorticity; it is a celebrated open problem whether this uniqueness result can be extended to the class of L^p-vorticities. In recent years, many contributions lead to significant progress: just to mention a few, there were results based on convex integration, on instability in self-similar variables, the study of certain point vortices, numerical evidences.

The talk will provide an overview of these developments and highlight new results showing that solutions obtained in the vanishing viscosity limit from the (well-posed) Navier-Stokes equations may be nonunique.

 

Speaker: Özlem Imamoglu (ETH Zurich)

 Title: Quadratic forms, quadratic fields and Modular functions

 Abstract: There are numerous connections between binary quadratic forms, quadratic fields and modular forms. One of the most beautiful is provided by the theory of singular moduli, which are the values of the Klein’s modular j-invariant at imaginary quadratic irrationalities. These values are known to be algebraic and have been studied extensively since the time of Kronecker and Weber.

In this talk I will give an overview of some of the old and new results and various applications of the connections between quadratic forms, quadratic fields and modular functions.
