The q-tetrahedron algebra realization conjecture for tridiagonal pairs

At least 21 years old · documented by

Assume K\mathbb K is algebraically closed. Let VV be a finite-dimensional vector space over K\mathbb K of positive dimension, and let A,A∗A,A^* be a tridiagonal pair on VV. Let β=q2+q−2\beta=q^2+q^{-2}, where β\beta is the scalar from the tridiagonal-pair relations, and assume that qq is not a root of unity. Let ⊠q\boxtimes_q be the qq-tetrahedron algebra. The q-tetrahedron algebra realization conjecture. There exists an irreducible ⊠q\boxtimes_q-module structure on VV such that AA acts as a linear combination of x01,x12,Ix_{01},x_{12},I, and A∗A^* acts as a linear combination of x23,x30,Ix_{23},x_{30},I. This would extend the established realization for tridiagonal pairs of qq-geometric type to the stated general setting. The supplied source gives no resolution.
