Title: Derived symplectic structures in Donaldson-Thomas theory and 
categorification

Abstract: We will speak about Donaldson-Thomas theory as a motivating 
example to introduce the theory of derived symplectic structures by 
Pantev, Toen, Vaquie and Vezzosi and the theory of derived critical loci 
by Joyce. We will then use these theories to prove a Darboux theorem for 
symplectic derived schemes and to construct on them perverse sheaves 
which are central in the problem of categorification.
This is a joint work with Ben-Bassat, Brav, Dupont, Joyce, Meinhardt and 
Szendroi.
