Subdivisions of vertex-disjoint cycles in bipartite graphs

Let $n\ge 6,k\ge 0$ be two integers. Let $H$ be a graph of order $n$ with $k$ components, each of which is an even cycle of length at least $6$ and $G$ be a bipartite graph with bipartition $(X,Y)$ such that $\mathrm{\mid }X\mathrm{\mid }=\mathrm{\mid }Y\mathrm{\mid }\ge n\mathrm{/}2$. In this paper, we show that if the minimum degree of $G$ is at least $n\mathrm{/}2-k+1$, then $G$ contains a subdivision of $H$. This generalized an older result of Wang.
