RTT presentation of finite š¯’²-algebras
C Briot, E Ragoucy Ā· Journal of Physics A Mathematical and General Ā· 2001
We construct a wide class of finite -algebras as truncations of Yangians. These truncations correspond to algebra homomorphisms and allow us to construct the -algebras as exchange algebras, the R -matrix being the Yangian one. As an application, we classify all irreducible finite-dimensional representations of these -algebras and determine their centre.
