Spectral conditions for graphs in which every edge belongs to a factor
Jin Cai, Bo Zhou
A factor of a graph is a spanning subgraph. Spectral sufficient conditions are provided via spectral radius and signless Laplacian spectral radius for graphs with (i) a matching of…

Spectral conditions for factor-criticality of graphs
Jin Cai, Bo Zhou
A graph is -factor-critical if has a perfect matching for any -subset of the vertex set of . In this paper, we investigate the factor-criticality of graphs w…
