Title: Problems and results on graphs of polytopes 



Abstract:




In the talk, we will discuss several results and problems related to graphs of polytopes. We will discuss  graph-theoretical properties of graphs of polytopes such as colouring, and vertex and edge connectivity. And we will present a perhaps not so well known application of graphs of polytopes to the classical problem of Minkowski decomposition of polytopes, which has its origins at Hebrew University through the PhD thesis of Michael Kallay in 1979! We will end with several open problems in this area.
