The q-tetrahedron algebra realization conjecture for tridiagonal pairs
Assume is algebraically closed. Let be a finite-dimensional vector space over of positive dimension, and let be a tridiagonal pair on . Let , where is the scalar from the tridiagonal-pair relations, and assume that is not a root of unity. Let be the -tetrahedron algebra. The q-tetrahedron algebra realization conjecture. There exists an irreducible -module structure on such that acts as a linear combination of , and acts as a linear combination of . This would extend the established realization for tridiagonal pairs of -geometric type to the stated general setting. The supplied source gives no resolution.
