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 ...

Bernoulli Lecture - Internal waves and homeomorphism of the circle

25 March 2021
Organisers :
  • Maciej Zworski
Please note that this event will take place on Zoom and the link will be posted here ahead of time.

The connection between the formation of internal waves in fluids and the dynamics of homeomorphisms of the circle was investigated by oceanographers in the 90s and resulted in novel experimental observations (Maas et al, ...

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

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

This event is cancelled and no rescheduling is planned.
We sincerely apologize for any inconvenience caused.
Thank you for your understanding.


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 ...

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 ...
