Abstract
A graph is called integral if all eigenvalues of its adjacency matrix are integers. Given a subset S
of a finite group G, the bi-Cayley graph BCay(G,S) is a graph with vertex set G×{1,2} and edge set {{(x,1),(sx,2)}∣s∈S,x∈G}. In this paper, we classify all finite groups admitting a connected cubic integral bi-Cayley graph.
