Seidel switching and graph energy

Haemers, Willem H. - 2012

The energy of a graph T is the sum of the absolute values of the eigenvalues of the adjacency matrix of T. Seidel switching is an operation on the edge set of T. In some special cases Seidel switching does not change the spectrum, and therefore the energy. Here we investigate when Seidel...
