Classification conjecture for arithmetic discrete groups from rigid DAHA modules

Let H\mathcal{H} and H\mathcal{H}^{\checkmark} denote the two DAHA-type algebras considered in the paper, and let Bq\mathcal{B}_q be the associated braid-group representation. Consider irreducible H\mathcal{H}-modules and irreducible H\mathcal{H}^{\checkmark}-modules on which XX and YY act semisimply. Identify representations up to isomorphism and up to changing the signs of the images of TT, YY, and XX. Classification conjecture. The arithmetic discrete non-finite groups Image(Bq)\operatorname{Image}(\mathcal{B}_q) can be only those appearing in the lists corresponding to

. This asserts that the displayed lists exhaust the arithmetic discrete non-finite groups arising under these hypotheses; the source provides no resolution status for the assertion.
