Title:

Topology of spaces of high-dimensional Legendrian knots.

Abstract:

The stable homotopy groups of Jean Cerf’s pseudoisotopy spaces and Friedhelm Waldhausen’s h-cobordism spaces can be injected into the homotopy groups of spaces of Legendrian submanifolds. In the I will l discuss the construction, the results and open problems. This is a joint work with Thomas Kragh.
