Real and complex invariant subspaces for matrices which are H-positive real in an indefinite inner product space
(ILAS, 2014)In this paper, the equivalence of the existence of unique real and complex A-invariant semidefinite subspaces for real H-positive real matrices are shown -
Simple forms and invariant subspaces of H-expansive matrices
(Elsevier, 2015)In this paper we consider a simple form for pairs of matrices (A,H)(A,H), where H is a real symmetric invertible matrix, and A is a real H -expansive matrix, that is, ATHA−HATHA−H is positive semidefinite. For such pairs ...
