Baxterisation of the fused Hecke algebra and R-matrices with gl(N)-symmetry

We give an explicit Baxterisation formula for the fused Hecke algebra and its classical limit for the algebra of fused permutations. These algebras replace the Hecke algebra and the symmetric group in the Schur–Weyl duality theorems for the symmetrised powers of the fundamental representation of gl ( N ) and their quantum version. So the Baxterisation formulas presented in this paper are applicable to the R -matrices associated with these representations. In particular, all “higher spins” representations of (classical and quantum) sl (2) are covered.
