报告摘要:Let $s$ and $t$ be two nonnegative integers. In 1996,Stiebitz confirmed a conjecture of Thomassen and showed that for every graph$G$ with $\delta(G)\ge s+t+1$ admits a bipartition $(A, B)$ such that$\delta(G[A])\ge s$ and $\delta(G[B])\ge t$. Then, some Stiebitz's type bound appearon special families of graphs. Very recently, Schweser and Stiebitz studied theanalogous problem on multigraphs (which may have parallel edges), andgeneralize some earlier results from simple graphs to multigraphs. We willbriefly introduce the history, recent progress and still open problem on thistopic.
