Lifting Graph Automorphisms by Voltage Assignments

open access: yesEuropean Journal of Combinatorics, 2000
The authors provide the first systematic combinatorial treatment of the automorphism lifting problem in the context of graphs. They make consistent use of several new fundamental concepts: the action of the fundamental groupoid, the notion of a voltage space, various kinds of invariance of voltage spaces, and the geometry of the lifted actions by means
