چکیده
|
In this paper, we construct a new class of integral bipartite graphs (not necessarily trees) with large even diameters. in fact, for every finite set a of positive integers of size k we construct an integral bipartite graph g of diameter 2k such that the set of positive eigenvalues of g is exactly a. this class of integral bipartite graphs has never found before.
