Primož Potočnik (University of Ljubljana):
Existence of a graph cover whose automorphism group is as we want it to be

Suppose one is given a finite connected graph X and a group of automorphisms G acting on it. Can one find a regular covering projection onto X such that G is the maximal group that lifts and such that the full automorphism group of the graph is the lift of G? A recent partial answer proved recently by Pablo Spiga and the speaker will be presented.
