Eigengaps for hub-dominant matrices

Research output: Contribution to journal › Article

Abstract

Hub-dominant matrices are natural extensions of hub matrices. In this article we study eigengaps of the Gram matrix associated with a hub-dominant matrix. A class of hub-dominant matrices is then constructed by using equiangular tight frames.
