Jordan-Schwinger Representations and Factorised Yang-Baxter Operators

[摘要] The construction elements of the factorised form of the Yang-Baxter R operator acting on generic representations of q -deformed sl ( n +1) are studied. We rely on the iterative construction of such representations by the restricted class of Jordan-Schwinger representations. The latter are formulated explicitly. On this basis the parameter exchange and intertwining operators are derived.
