Refined inertias of positive and hollow positive patterns
We investigate refined inertias of positive patterns and patterns that have each off-diagonal entry positive and each diagonal entry zero, i.e., hollow positive patterns. For positive patterns, we prove that every refined inertia (n+,n−,nz,2np)\left({n}_{+},{n}_{-},{n}_{z},2{n}_{p}) with n+≥1{n}_{+}...
