Type $\tilde{C}$ Temperley-Lieb algebra quotients and Catalan combinatorics (1904.08351v1)
Published 17 Apr 2019 in math.CO, math.RA, and math.RT
Abstract: We study some algebraic and combinatorial features of two algebras that arise as quotients of Temperley-Lieb algebras of type $\tilde{C}$, namely, the two-boundary Temperley-Lieb algebra and the symplectic blob algebra. We provide a monomial basis for both algebras. The elements of these bases are parameterized by certain subsets of fully commutative elements. We enumerate these elements according to their affine length.
