Abstract

This project for a Ph.D. thesis focuses on groupoid graded rings with two main topics. On the one hand, we will study the existence of graded homomorphisms from a groupoid graded ring to groupoid graded division rings, i.e. we intend to extend Cohn's theory to this setting as well as the result of Malcomsom and Schofield on homomorphisms of rings to division rings. On the other hand, we will study the connection between several rings and categories associated to groupoid graded rings.
