Noncommutative algebraic geometry

Yakov Kremnitzer
Abstract

There are several different approaches to noncommutative algebraic geometry. I will present one of these approaches. A noncommutative space will be an (abelian) category. I will show how to associate a ringed space to a category. In the case of the category of quasi-coherent sheaves on a scheme this construction will recover the scheme back. I will also give examples coming from quantum groups.
