    • ON RENORMALIZATION OF POISSON–LIE TPLURAL SIGMA MODELS 

      Author: Hlavatý , Ladislav; Navrátil , Josef; Šnobl , Libor
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      Covariance of the one-loop renormalization group equations with respect to Poisson–Lie T-plurality of sigma models is discussed. The role of ambiguities in renormalization group equations of Poisson–Lie sigma models with ...
    • PROPOSAL OF NEW OPTICAL ELEMENTS 

      Author: Chadzitaskos , Goce; Tolar , Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      A overview of our patented proposals of new optical elements is presented. The elements are suitable for laser pulse analysis, telescopy, X-ray microscopy and X-ray telescopy. They are based on the interference properties ...
    • RESONANCES ON HEDGEHOG MANIFOLDS 

      Author: Exner , Pavel; Lipovský , Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      We discuss resonances for a nonrelativistic and spinless quantum particle confined to a two- or three-dimensional Riemannian manifold to which a finite number of semiinfinite leads is attached. Resolvent and scattering ...
    • THE NUMBER OF ORTHOGONAL CONJUGATIONS 

      Author: Uhlmann , Armin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      After a short introduction to anti-linearity, bounds for the number of orthogonal (skew) conjugations are proved. They are saturated if the dimension of the Hilbert space is a power of two. For other dimensions this is an ...
    • THE SHMUSHKEVICH METHOD FOR HIGHER SYMMETRY GROUPS OF INTERACTING PARTICLES 

      Author: Bodner , Mark; Chadzitaskos , Goce; Patera , Jiří; Tereszkiewitz , Agnieszka
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      About 60 years ago, I. Shmushkevich presented a simple ingenious method for computing the relative probabilities of channels involving the same interacting multiplets of particles, without the need to compute the Clebsch-Gordan ...
