Spectral radius and rainbow $k$ -factors in a bipartite graph family

Meng Chen, Ruifang Liu

Let $G = {G_{1}, G_{2}, \dots, G_{k n}}$ be a family of balanced bipartite graphs on the same vertex set $[2 n]$ . A rainbow $k$ -factor of $G$ is defined as a $k$ -fa…

Spectral radius and rainbow Hamiltonicity in bipartite graphs

Meng chen, Ruifang Liu, Qixuan Yuan

Let $G = {G_{1}, G_{2}, \dots, G_{k}}$ be a family of bipartite graphs on the same vertex set. A rainbow Hamilton path (cycle) in $G$ is a path (cycle) that visits…
