    • Dilations of some VH-spaces operator valued invariant Kernels 

      Gheondea, A. (Springer, 2012)
      We investigate VH-spaces (Vector Hilbert spaces, or Loynes spaces) operator valued Hermitian kernels that are invariant under actions of *-semigroups from the point of view of generation of *-representations, linearizations ...
    • The three equivalent forms of completely positive maps on matrices 

      Gheondea, A. (Editura Universitatea din Bucuresti, 2010)
      Motived by the importance of quantum operations in quantum information theory, we rigorously present the three equivalent (Stinespring, Kraus, and Choi) forms of completely positive maps on full C∗-algebras of matrices, ...
