Distance spectral conditions for $ID$-factor-critical and fractional $[a,b]$-factor of graphs

Tingyan Ma, Ligong Wang

Let $G=(V(G),E(G))$ be a graph with vertex set $V(G)$ and edge set $E(G)$. A graph is $ID$-factor-critical if for every independent set $I$ of $G$ whose size has the same parity a…
