Random Lifts of Graphs: Edge Expansion

  • ALON AMIT (a1) and NATHAN LINIAL (a2)
Abstract

We continue the study of random lifts of graphs initiated in [4]. Here we study the possibility of generating graphs with high edge expansion as random lifts. Along the way, we introduce the method of $\epsilon$-nets into the study of random structures. This enables us to improve (slightly) the known bounds for the edge expansion of regular graphs.
