Spectral radius for the existence of $H_{b}$ -factors in binding graphs

Sufang Wang, Wei Zhang

The binding number, denoted by $\mbox{bind}(G)$, of a graph $G$ is defined as the minimum value of $\frac{∣ N _{G} ( X ) ∣}{∣ X ∣}$ taken over any non-empty subset $X$ of $V (G)$ with $N_G(X)…

Distance spectral radius for a graph to be k-critical with respect to [1,b]-odd factor

Sufang Wang, Wei Zhang

Let $G$ be a connected graph, and let $b$ and $k$ be two positive integers with $b \equiv 1$ (mod 2). A $[1, b]$ -odd factor of $G$ is a spanning subgraph $F$ of $G$ with $d_F(v)\equiv…
