摘要：

We prove that every bipartite graph of sufficiently large average degree has either a Kt,t-subgraph or an induced subgraph of average degree at least t and girth at least 6. We conjecture that "6" can be replaced by any constant "k," which strengthens a conjecture of Thomassen. In support of this conjecture, we show that it holds for regular graphs.
