Independence number and connectivity for fractional (a,b,k)-critical covered graphs

Sizhong Zhou, Jiancheng Wu, Hongxia Liu

A graph $G$ is a fractional $(a,b,k)$-critical covered graph if $G-U$ is a fractional $[a,b]$-covered graph for every $U\subseteq V(G)$ with $|U|=k$, which is first defined by Zhou…
