Salle conference (LJAD)

In this talk, I will describe recent progress on the analysis of high frequencies for subelliptic operators, highlighting how techniques from Lie group analysis and harmonic analysis can be adapted to this non-elliptic context. I will present some representative results and explain how they connect with microlocal and semiclassical approaches, pointing to several open problems.
