ABSTRACT
Linear operators R are introduced on tensor products of evaluation modules of U'q(sl(2)) obtained from the complementary and strange series representations. The operators R satisfy the intertwining condition on finite linear combinations of the canonical basis elements of the tensor products. Infinite sums associated with the action of R on six pairs of tensor products are evaluated. For two pairs, the sums are related to the vector-valued big q-Jacobi transform of the matrix elements defining the operator R. In one case, the sums specify the action of R on the irreducible representations present in the decomposition of the underlying indivisible sum of U'q(sl(2))-tensor products. In both cases, bilinear summation formulae for the matrix elements of R provide a generalization of the unitarity property. Corresponding results are given for the remaining pairs.

    We construct the bosonization of the Fock space F⊗½ of a single neutral fermion by using a 2-point local Heisenberg field. We decompose F⊗½ as a direct sum of irre-ducible highest weight modules for the Heisenberg algebra HZ, and thus we show that under the Heisenberg HZ action...
