Applications of analysis to the determination of the minimum number of distinct eigenvalues of a graph
Beth Bjorkman, Leslie Hogben, Scarlitte Ponce +2
We establish new bounds on the minimum number of distinct eigenvalues among real symmetric matrices with nonzero off-diagonal pattern described by the edges of a graph and apply th…
