Abstract

Convex quadratic programming upper bounds on the size of k-regular induced subgraphs are analyzed and a necessary and sufficient condition for such upper bounds being tight is introduced. Based on this approach, new spectral upper bounds on the order of maximum size k-regular induced subgraphs are deduced. Related open problems and a few computational experiments are presented.
