Disjoint cycles covering specified vertices in bipartite graphs with partial degrees

Suyun Jiang, Jin Yan

Let $k$ be a positive integer. Let $G$ be a balanced bipartite graph of order $2 n$ with bipartition $(X, Y)$ , and $S$ a subset of $X$ . Suppose that every pair of nonadjacent vertic…

On directed version of the Sauer-Spender Theorem

Yun Wang, Jin Yan

Let $D = (V, A)$ be a digraph of order $n$ and let $W$ be any subset of $V$ . We define the minimum semi-degree of $W$ in $D$ to be $δ^0(W)=\mbox{min}\{δ^+(W),δ^-(W)\}$, where $δ^{+} (W)$ …
