论文摘要
我们证明,每个两分的平均水平图都具有$ k_ {t,t} $ - 子图或平均程度的诱发子图,至少$ t $和腰围至少至少$ 6 $。我们猜想“ $ 6 $”可以用“ $ k $”代替,这加强了托马森的猜想。为了支持这种猜想,我们证明它适用于常规图。
We prove that every bipartite graph of sufficiently large average degree has either a $K_{t,t}$-subgraph or an induced subgraph of average degree at least $t$ and girth at least $6$. We conjecture that "$6$" can be replaced by "$k$", which strengthens a conjecture of Thomassen. In support of this conjecture, we show that it holds for regular graphs.
