摘要
Zarankiewicz proposed the problem of determining the maximum number of edges in an (n, m)-bipartite graph containing no complete bipartite graph K-a,K-b. In this paper, we consider a variant of Zarankiewicz's problem and determine the maximum number of edges of an (n, m)-bipartite graph without containing a linear forest consisting of even paths. Moveover, all these extremal graphs are characterized in a recursion way.
