ERC Consolidator grant project IPFLOW
Principal Investigator : Colin Guillarmou
Postdoc: Benjamin Kuster (2018-2020)
Other members of the group: Thibault Lefeuvre (PhD 2017-2020), Yann Chaubet (PhD 2018-2020)
subject of the ERC project is Inverse Problems and the analytic study
of flows (Anosov flows, Axiom A flows, geodesic flows etc).
We aim to study :
* X-ray transform and boundary rigidity problems: can we recover a
function/tensor from its integrals along geodesics ? Can we
recover a metric from the length of its geodesics ?
* Ruelle resonance spectrum for hyperbolic flows and long time dynamics.
* Microlocal methods for problems on flows, like rigidity questions.
* June 26-30, 2017: Summer school: Microlocal Analysis and Applications in Cardiff
* July 3-7, 2017: Summer school: Analytical aspects of hyperbolic flows
* February 7-8-9, 2018: mini workshop/working group seminars in Orsay
* June 4-8, 2018: workshop Analytic Study of Flows, Peyresq
* December 10-12, 2018: mini workshop/working group seminars in Orsay
