Homological projective geometry

**Abstract:**I will discuss some surprising "homological" counterparts of constructions and results in classical projective geometry. This gives a powerful framework for producing varieties whose derived categories are equivalent, or more generally have a large subcategory in common. Besides being of intrinsic interest, such relations often have strong geometric consequences. This is joint work with Alexander Kuznetsov.
