DisCoMath Seminar: Orthogonal matrices with zero diagonal
Discrete & Computational Math Seminar (DisCoMath)
Orthogonal matrices with zero diagonal
Dr. Darren Narayan
Professor
School of Mathematical Sciences, RIT
Abstract:
A presentation will be given on the paper "On orthogonal matrices with zero diagonal" by R. Bailey and R. Craigen. In this paper the authors consider real orthogonal n×n matrices whose diagonal entries are zero and off-diagonal entries nonzero. They use these results to determine the minimum number of distinct eigenvalues of matrices associated with some families of graphs, and consider the related notion of orthogonal matrices with a partially-zero diagonal.
