Signless Laplacian spectral conditions for rainbow matchings in a collection of bipartite graphs

Zhiwei Guo, Nanxi Pan, Li Li +1

Let $\mathcal{G}=\{G_1,\dots ,G_k\}$ be a collection of (not necessarily distinct) bipartite graphs on the same vertex bipartition $(X,Y)$, where $|X|=a$, $|Y|=b$ and $2\le k\le a\le…
