--deformed Wigner construction of relativistic wave functions and free fields on -Minkowski space
P. Kosiński, J. Lukierski, P. Maślanka
We describe the extension of the Wigner`s infinite-dimensional unitary representations of Poincaré group to the case of -deformed Poincaré group. We show that the corresponding…

Calogero model and sL(2,R) algebra
C. Gonera, P. Kosinski
The Calogero model with external harmonic oscillator potential is discussed from sL(2,R) algebra point of view. Explicit formulae for functions with exponential time behaviour are…

-Deformation of Poincaré Superalgebra with Classical Lorentz Subalgebra and its Graded Bicrossproduct Structure
P. Kosi{ń}ski, J. Lukierski, P. Ma{ś}lanka +1
The -deformed Poincar{é} superalgebra written in Hopf superalgebra form is transformed to the basis with classical Lorentz subalgebra generators. We show that in such a ba…
