Abstract

In this paper we define extended corona and extended neighborhood corona of two graphs G₁ and G₂, which are denoted by G₁ • G₂ and G₁ * G₂ respectively. We compute their adjacency spectrum, Laplacian spectrum and signless Laplacian spectrum. As applications, we give methods to construct infinite families of integral graphs, Laplacian integral graphs and expander graphs from known ones.
