A. Ballesteros et al., UNIVERSAL R-MATRICES FOR NONSTANDARD (1+1) QUANTUM GROUPS, Journal of physics. A, mathematical and general, 28(11), 1995, pp. 3129-3138
A universal quasi-triangular R-matrix for the non-standard quantum (11) Poincare algebra U(z)iso(1, 1) is deduced by imposing analyticity i
n the deformation parameter z. A family U-omega g mu of 'quantum grade
d contractions' of the algebra U(z)iso(1, 1) + U(-z)iso(1, 1) is obtai
ned. Quantum analogues of the two-dimensional Euclidean, Poincare and
Galilei algebras enlarged with dilations are contained in U-omega g mu
as Hopf subalgebras with two primitive translations. Universal R-matr
ices for these quantum Weyl (similitude) algebras and their associated
quantum groups are constructed.
