Linear Response: Rigorous Results and Applications  25 - 29 January 2021

08:00 - 17:00
Room : GA 3 21

Organisers

Wael Bahsoun, Loughborough University

Viviane Baladi, CNRS and Sorbonne University

Stefano Galatolo, Università di Pisa

Nina Gantert, Technical University of Munich

As per new sanitary recommendations, this event will take place 100% online.


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 the presence of singularities.
