Two Boundary Centralizer Algebras for $\mathfrak{q}(n)$
Abstract
We define the degenerate two boundary affine Hecke-Clifford algebra , and show it admits a well-defined -linear action on the tensor space , where is the natural module for , and are arbitrary modules for , the Lie superalgebra of Type Q. When and are irreducible highest weight modules parameterized by a staircase partition and a single row, respectively, this action factors through a quotient of . We then construct explicit modules for this quotient, , using combinatorial tools such as shifted tableaux and the Bratteli graph. These modules belong to a family of modules which we call calibrated. Using the relations in , we also classify a specific class of calibrated modules. The irreducible summands of coincide with the combinatorial construction, and provide a weak version of the Schur-Weyl type duality.
