| contents | Skein algebras of surfaces quantize character varieties of topological surfaces, and in low genus, these quantizations are often related to algebras arising in representation theory. For example, Terwilliger defined a universal $SL_2$ spherical double affine Hecke algebra $A$; a combination of results in the literature shows $A$ is isomorphic to the $SL_2$ skein algebra of the punctured torus.
Stated skein algebras are a generalization which quantize decorated character varieties. In this paper, we used stated skein algebras to construct a new embedding of $A$ into a rank 6 quantum torus, and we show that each marked 3-manifold with a torus boundary produces a module over $A$. We also determine a generating set for the stated skein algebra of $T^2\setminus D^2$, and we find many relations; however, finding a complete list of relations is still an open problem. |
