Abstract

This paper investigates the spectral radius and signless Laplacian spectral radius of linear uniform hypergraphs. A dominating set in a hypergraph H is a subset D of vertices if for every vertex v not in D there exists $$u\in D$$ u ∈ D such that u and v are contained in a hyperedge of H. The minimum cardinality of a dominating set of H is called the domination number of H. We present lower bounds on the spectral radius and signless Laplacian spectral radius of a linear uniform hypergraph in terms of its domination number.
