Irreducible Representations of an Algebra underlying Hidden Symmetries of a class of Quasi Exactly Solvable Systems of Equations
Y. Brihaye, S. Giller, P. Kosinski +1
The set of linear, differential operators preserving the vector space of couples of polynomials of degrees n and n-2 in one real variable leads to an abstract associative graded al…
On the relations between osp(2,2) and the quasi exactly solvable systems
Yves Brihaye, Stefan Giller, Piotr Kosinski
By taking a product of two sl(2) representations, we obtain the differential operators preserving some space of polynomials in two variables. This allows us to construct the repres…
A note on geometry of Kappa-Minkowski space
Stefan Giller, Cezary Gonera, Piotr Kosinski +1
The infinitesimal action of Kappa-Poincar'e group on Kappa-Minkowski space is computed both for generators of Kappa-Poincar'e algebra and those of Woronowicz generalized Lie algebr…
Deformation map for generalized Kappa-Poincar'e and Kappa-Weyl algebras
Stefan Giller, Cezary Gonera, Michal Majewski
A nonlinear transformation in the momentum space is constructed which converts the deformed action of Lorentz and Weyl generators on momenta into the standard one.
