R-matrice universelle pour U_h (D(2, 1, x)) et invariant d'entrelcas associe

摘要

Using the quantum double method, we construct a universal R-matrix for the quantization of the Lie superalgebra D(2, 1, x). We use this result to construct a link invariant and show it coincides with a specialization of Kauffman's Dubrovnik polynomial.
