    • Dilation theorems for VH-spaces 

      Uğurcan, Barış Evren (Bilkent University, 2009)
      In the Appendix of the book Le¸cons d’analyse fonctionnelle by F. Riesz and B. Sz.-Nagy, B. Sz.-Nagy [15] proved an important theorem on operator valued positive definite maps on ∗-semigroups, which today can be considered ...
    • 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 ...
