Exponential mapping for non semisimple quantum groups
F. Bonechi, Enrico Celeghini, R. Giachetti +3
The concept of universal T matrix, recently introduced by Fronsdal and Galindo in the framework of quantum groups, is here discussed as a generalization of the exponential mapping.…
Italian workshop on quantum groups
Enrico Celeghini, M. Tarlini
The first ``Convegno Informale su Quantum Groups'' was held in Florence from February 3 to 6, 1993. This Convegno was conceived as an informal meeting to bring together all the ita…
The Quantum Deformed Dirac Equation from the k-Poincare` Algebra
Anatol Nowicki, Emanuele Sorace, Marco Tarlini
In this letter we derive a deformed Dirac equation invariant under the k-Poincare` quantum algebra. A peculiar feature is that the square of the k-Dirac operator is related to the…
Heisenberg XXZ Model and Quantum Galilei Group
F. Bonechi, E. Celeghini, R. Giachetti +2
The 1D Heisenberg spin chain with anisotropy of the XXZ type is analyzed in terms of the symmetry given by the quantum Galilei group Gamma_q(1). We show that the magnon excitations…
