Bicrossproduct structure of the null-plane quantum Poincare algebra
Oscar Arratia, Francisco J. Herranz, Mariano A. del Olmo
A nonlinear change of basis allows to show that the non-standard quantum deformation of the (3+1) Poincare algebra has a bicrossproduct structure. Quantum universal R-matrix, Pauli…
Contractions on the Classical Double
Angel Ballesteros, Mariano del Olmo
Lie algebra contractions on the classical Drinfel'd Double of a given Lie bialgebra are introduced and compared to the usual Lie bialgebra contraction theory. The connection betwee…
Null-plane Quantum Poincaré Algebras and their Universal -matrices
A. Ballesteros, F. J. Herranz, M. A. del Olmo +1
A non-standard quantum deformation of the Poincaré algebra is presented in a null-plane framework for 1+1, 2+1 and 3+1 dimensions. Their corresponding universal -matrices are ob…
