The signless Laplacian spectral radius of graphs without intersecting odd cycles

Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang

Let $F_{a_{1}, \dots, a_{k}}$ be a graph consisting of $k$ cycles of odd length $2 a_{1} + 1, \dots, 2 a_{k} + 1$ , respectively which intersect in exactly a common vertex, where $k \geq 1$ and $a_1\g…

On the spectral radius of graphs without a star forest

Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang

In this paper, we present two sharp upper bounds for the spectral radius of (bipartite) graphs with forbidden a star forest and characterize all extremal graphs. Moreover, the mini…
