EMS Women in Mathematics Day 2022

 [expired]

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, 20 May 2022 with the following schedule:

  • 14:45 CEST Welcome
  • 15:00 CEST Tara Brendle (Glasgow University, UK)
  • 16:00 CEST Tere M. Seara (UPC, Barcelona, Spain)

The titles and abstracts of the talks are given below.

Any interested person may attend via Zoom (passcode 216273). Please, forward the information to your contacts, and circulate it as widely as possible.

Best wishes from the EMS/WiM Committee,

Shiri Artstein, Alessandra Celletti, Maria del Mar Gonzalez, Mikaela Iacobelli, Stanislava Kanas, Marjeta Kramar Fijavz, Isabel Labouriau, Pablo Mira, Jiri Rakosnik, Elena Resmerita, Anne Taormina

Titles and abstracts

  • Tara Brendle (Glasgow University, UK): Symmetries of manifolds

    Abstract: Riemann introduced manifolds in the mid-19th century as a mechanism for understanding n-dimensional space. Landmark achievements in mathematics since then include the classification of 2-manifolds in the early 20th century as well as the more recent (though more complicated) classification of 3-manifolds completed by Perelman. However, the story does not end with classification: there is a rich theory of symmetries of manifolds, encoded in their mapping class groups. In this talk we will explore some aspects of mapping class groups in dimensions 2 and 3, with a focus on illustrative examples.

  • Tere M. Seara (UPC, Barcelona, Spain) Arnold diffusion: an overview and recent results

    Abstract: In this talk I will talk about the phenomenon known as Arnold diffusion. Equivalently we will show the mechanism that creates big effects after applying arbitrarily small forces for a sufficiently large time. In the language of Hamiltonian Systems, we will consider small periodic in time perturbations of an integrable system. It is known that the energy is preserved in an integrable system, as well as other quantities known as actions. We will show that an arbitrarily small perturbation can create big increments in the energy (and in the actions) and we will explore the dynamic mechanism that is behind this phenomenon.
