Title：The Aα-spectral radius and k-matching number in graphs

Abstract：A k-matching is a subgraph induced by the edges with weight among 0,1,⋯,k such that ∑e~vfe≤k for every vertex v∈V(G). when k is odd, we give a relationship between Aα-spectral radius and integer k-matching number in general graphs by using the analogous approach given by R. F. Liu et al. (2020).
