"Constructions of generalized complex structures of different
type".

Abstract: The talk is a survey on recent existence results of
generalized complex structures in dimension four. We begin with a brief
introduction to generalized complex geometry. Then, we move on to
discuss recent cut-and-paste constructions on smooth 4-manifolds that
have unveiled interesting phenomena regarding existence results on a
myriad of manifolds, and information on the number of path components of 
the type change locus of a generalized complex structure, hence
improving drastically our understanding of these geometric structures.
The talk will be example-driven.

"Separability properties of 3-manifold groups and symplectic 4-manifolds"

Abstract: I will survey some results on 3-manifold groups and discuss 
how they allow us to decide the existence of symplectic structures on 
some classes of 4-manifolds
