摘要：
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 a tight spectral radius condition for graphs being fractional [a, b]-covered. (c) 2023 Elsevier Inc. All rights reserved.
