NOUVELLES DATES - Spectra in Riemannian and Symplectic Geometry

Lieu

Zanjan, Iran

Dates

03/07/2021 - 14/07/2021

Présentation

One of the fascinating bridges between  classical  mechanics  and quantum physics  is expressed  in the fact that the length spectrum  and the Laplace  spectrum  of a closed Riemannian  manifold determine  each other (at least generically). The main goal of this school  is to introduce  graduate  students  and young  researchers to basic facts on these two spectra, and to the above correspondence.

The length spectrum  generalizes   to the action spectrum  of an autonomous Hamiltonian function.  Floer homofogy filtered  by the action spectrum  can be used to construct  so-called  action selectors,  that are a principal  tool in modern symplectic  geometry and dynamics.

The second goal is to understand  this relevance  of the action spectrum  in symplectic geometry.

A third,  more hypothetical, goal is to see which parts  of the two sides can be related.

Langue officielle de l'école : anglais.
