On the spectral radius of nonregular uniform hypergraphs

Combinatorics 2015-12-01 v1

Abstract

Let GG be a connected uniform hypergraphs with maximum degree Δ\Delta, spectral radius λ\lambda and minimum H-eigenvalue μ\mu. In this paper, we give some lower bounds for Δλ\Delta-\lambda, which extend the result of [S.M. Cioab\u{a}, D.A. Gregory, V. Nikiforov, Extreme eigenvalues of nonregular graphs, J. Combin. Theory, Ser. B 97 (2007) 483-486] to hypergraphs. Applying these bounds, we also obtain a lower bound for Δ+μ\Delta+\mu.
