CANCELLED : Geometry and dynamics of totally disconnected locally compact groups

14 - 18 December 2020
Organisers :
  • Uri Bader
  • Pierre-Emmanuel Caprace
  • Yves Cornulier
  • Katrin Tent
  • George Willis

Following recent developments and in accordance with the restrictions imposed by our authorities and the EPFL, this event is cancelled.

T.d.l.c. groups can generally be realised as groups of isometries of locally finite connected graphs, and this viewpoint brings geometry to the investigation of t.d.l.c. groups. Not only ...

Linear Response: Rigorous Results and Applications

25 - 29 January 2021
Organisers :
  • Wael Bahsoun
  • Viviane Baladi
  • Stefano Galatolo
  • Nina Gantert
  • Georg Gottwald

Transfer operators have been used to study rare and extreme events in dynamical systems and the linear - or nonlinear - response of systems to perturbations, including applications to climate dynamics.

This conference brings together experts from both theoretical and applied aspects of these studies, also in ...

Bernoulli Lecture - Towards a mathematical model of the brain

28 January 2021
Organisers :
  • Lai-Sang Young

Striving to make contact with mathematics and to be consistent with neuroanatomy at the same time, I propose an idealized picture of the cerebral cortex consisting of a hierarchical network of brain regions each further subdivided into interconnecting layers not unlike those in artificial neural networks. Each layer is idealized as a ...

Ruelle-Pollicott Resonances in Dynamics and in Semi-classical Analysis

12 - 16 April 2021
Organisers :
  • Viviane Baladi
  • Colin Guillarmou
  • Masato Tsujii

This conference brings together experts who study Ruelle-Pollicott resonances by using semiclassical and dynamical approaches.

Topics range from the Fried conjectures and other geometrical conjectures to various approaches to construct anisotropic spaces and strategies to obtain spectral gaps and essential spectral gaps, including the fractal uncertainty principle, and addressing non ...

Transfer Operators Beyond Smooth or Uniformly Hyperbolic Systems

07 - 11 June 2021
Organisers :
  • Viviane Baladi
  • Mark Demers
  • Sébastien Gouëzel
  • Carlangelo Liverani
  • Françoise Pène

There has recently been an explosion of results about transfer operators acting on anisotropic Banach spaces, starting with correlation decay and the analyticity properties of the Ruelle dynamical zeta function of uniformly hyperbolic maps and flows. These techniques have been extended to hyperbolic systems withsingularities, but the results there ...
