    • Generic rank-k perturbations of structured matrices 

      Batzke, Leonhard; Ran, André C.M.; Rodman, Leiba; Mehl, Christian (Springer, 2016)
      This paper deals with the effect of generic but structured low rank perturbations on the Jordan structure and sign characteristic of matrices that have structure in an indefinite inner product space. The paper is a follow-up ...
    • mth Roots of H-selfadjoint matrices 

      Groenewald, G.J.; Janse van Rensburg, D.B.; Ran, A.C.M.; Theron, F.; Van Straaten, M. (Elsevier, 2021)
      In this paper necessary and sufficient conditions are given for the existence of an H-selfadjoint mth root of a given H-selfadjoint matrix. A construction is given of such an Hselfadjoint mth root when it does exist
