Minimizing the spectral radius of unicyclic graphs with fixed order and dissociation number
A dissociation set of a graph G is a vertex subset S contained in V(G) such that the induced subgraph G[S] has maximum degree at most 1, and the dissociation number of G is the cardinality of a maximum dissociation set denoted by {\Phi}(G). In this paper, we first derive a sharp lower bound on the dissociation number f...
