Koszul and Quadratic Duality with Applications

ABSTRACT:  I will explain the concept of Koszul and quadratic algebras, give several examples where such algebras naturally appear and then  explain the problems which occur when the algebras are infinite dimensional. A general quadratic duality functor is constructed which coincides with the Koszul duality in case the algebras are Koszul. The different t-structures in the derived categories are made explicit.
