Topic: Homomorphisms of signed graphs

Speaker: Reza Naserasr

Abstract: Homomorphisms of signed graphs has been recently introduced as extension of homomorphisms of graphs. One of the main motivations is that it provides room for a stronger connection between the theories of minor and coloring of graphs.

In this talk I will introduce the notion, present some motivating problems, and some proof techniques.
