Monotone Lagrangians in cotangent bundles of spheres.
Abstract: We show that there is a 1-parameter family of monotone Lagrangians in
cotangent bundles of spheres with the following property: every
(orientable spin) closed monotone Lagrangian with non-trivial Floer
cohomology is not Hamiltonian-displaceable from either the zero-section
or one of the Lagrangians in the family. The proof involves studying a
version of the wrapped Fukaya category that includes monotone
Lagrangians. This is joint work with Mohammed Abouzaid.

Constructions of Legendrian knots and cobordisms together with
generating functions .
Abstract: Among all Legendrian knots in the space JR,R) = R x T*R,
some can be obtained from graphs of functions by a classic and natural
operation~: by taking the contour of generating functions. We focus on
this very restrictive class of Legendrians, and offer constructions to
help studying them. In this talk, we will discuss in particular the
related notion of cobordism~: that is Legendrian surfaces between
Legendrian knots which are also contour of generating functions.1(
