On the spectral properties of square matrices that are strictly sign-regular of some order k

  • A matrix is called strictly sign-regular of order k (SSR_k) if all its k-by-k minors are nonzero and have the same sign. In this poster, the spectral properties of nonsingular matrices which are SSR_k for a specific value k are studied.
