Title of talk: Sheaves and quivers, 2:00
 
Abstract: Recently, motivated and inspired by developments in Physics  (string theory), there has been a lot of interest in the derived  categories 
of coherent sheaves of algebraic varieties. Some recent  breakthroughs
 include the facts that in some cases, a variety can be  determined by its 
derived category, in other cases, this is far from  being true. This is 
currently an extremely active and important area of  research. In this 
VIGRE group our aim will be to gain a working  knowledge of derived
 categories by computing them for concrete  examples. For instance, the
 derived categories of Del Pezzo surfaces  have beautiful and simple
 descriptions. We will attempt to generalize  some of these descriptions
 to new cases of varieties.
