PIRSA Number: 


will describe a new method for understanding a large class of

generalized complex manifolds, in which we view them as usual

symplectic structures on a manifold with a kind of log structure. I

will explain this structure in detail and explain how it can be used

to prove a Tian-Todorov unobstructedness theorem as well as

topological obstructions for existence of nondegenerate generalized

complex structures.
