Non-commutative algebraic geometry of semi-graded rings

Oswaldo Lezama

Universidad Nacional de Colombia, Bogotá, Colombia, Colombia   -

In this short talk we introduce the semi-graded rings, which generalize graded rings and skew PBW extensions. For this new type of non-commutative rings we will study some basic problems of non-commutative algebraic geometry. In particular, we will discuss the Serre-Artin-Zhang-Verevkin theorem about non-commutative schemes.

Joint work with Edward Latorre (Universidad Nacional de Colombia, Bogotá, Colombia).
