论文摘要
图$ g $称为分数$ [a，b] $ - 如果对于每个边缘$ e $ g $ of $ g $，则有一个分数$ [a，b] $ - 带有指标函数$ h $的因子，因此$ h（e）= 1 $。在本文中，我们为图形$ [a，b] $ - 覆盖的图形提供了紧密的光谱半径条件。
A graph $G$ is called fractional $[a,b]$-covered if for every edge $e$ of $G$ there is a fractional $[a,b]$-factor with the indicator function $h$ such that $h(e)=1$. In this paper, we provide tight spectral radius conditions for graphs being fractional $[a,b]$-covered.
