IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

The Birkhoff attractor is a closed invariant subset associated with any dissipative twist map of the annulus (of dimension 2), which was introduced by Birkhoff in 1932. We will see that it can be generalized to higher dimensions using tools from symplectic topology, namely the spectral distance and the gamma-support. This is based on joint work with Marie-Claude Arnaud and Claude Viterbo.
