    • Simple forms and invariant subspaces of H-expansive matrices 

      Fourie, J.H.; Groenewald, G.J.; Janse van Rensburg, D.B.; Ran, A.C.M. (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 ...
