ON RENORMALIZATION OF POISSON–LIE T-PLURAL SIGMA MODELS
(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
(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 ...
THE SHMUSHKEVICH METHOD FOR HIGHER SYMMETRY GROUPS OF INTERACTING PARTICLES
(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 ...
RESONANCES ON HEDGEHOG MANIFOLDS
(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 ...
EXTREMAL VECTORS FOR VERMA TYPE REPRESENTATION OF B2
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Starting from the Verma modules of the algebra B2 we explicitly construct factor representations of the algebra B2 which are connected with the unitary representation of the group SO(3, 2). We find a full set of extremal ...
