Universal R-matrices for non-standard (1+1) quantum groups
A universal quasi-triangular R-matrix for the non-standard quantum (1+1) Poincare algebra Uziso(1,1) is deduced by imposing analyticity in the deformation parameter z. A family Uwgmu of 'quantum graded contractions' of the algebra Uziso(1,1)(+)U-ziso(1,1) is obtained. Quantum analogues of the two-dimensional Euclidean, Poincare and Galilei algebras enlarged with dilations are contained …
