A central extension of Uq sl(2,2)(1) and R-matrices with a new parameter
Abstract
In this paper, using a quantum superalgebra associated with the universal central extension of sl(2,2)(1), we introduce new R-matrices having an extra parameter x. As x 0, they become those associated with the symmetric and anti-symmetric tensor products of the copies of the vector representation of Uq sl(2,2)(1).
