The inertia of certain Hermitian block matrices
Description
We characterize sets of inertias of some partitioned Hermitian matrices by a system of inequalities involving the orders of the blocks, the inertias of the diagonal blocks, and the ranks of the nondiagonal blocks. The main result generalizes some well-known characterizations of Sá and Cain and others. http://www.sciencedirect.com/science/article/B6V0R-3T0XRRS-B/1/8d3bd399ae513d7f09da6e4906334dea
