The classical basis for -deformed Poincaré (super)algebra and the second -deformed supersymmetric Casimir
P. Kosiński, J. Lukierski, P. Maślanka +1
We present here the general solution describing generators of \kdef \poin algebra as the functions of classical \poin algebra generators as well as the inverse formulae. Further we…
-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…
TQFT versus RCFT: 3-d topological invariants
Boguslaw Broda
A straightforward relationship between the two approaches to 3-dimensional topological invariants, one of them put forward by Witten in the framework of topological quantum field t…
Quantum Deformation of the Poincare Supergroup and -deformed Superspace
P. Kosi{ń}ski, J. Lukierski, P. Ma{ś}lanka +1
The classical -matrix for superPoincar{é} algebra, given by Lukierski, Nowicki and Sobczyk is used to describe the graded Poisson structure on the Poincar{é} supergr…
