Abstract
- For two positive integers a and b with a ≤ b , an [ a , b ] -factor of a graph is a spanning subgraph of the graph such that the degree of each vertex in the subgraph is between a and b. Recently, Cho, Hyun, O and Park posed a conjecture for the existence of [ a , b ] -factors in graphs under a spectral radius condition. We confirm this conjecture in this paper.
