Explicit representations of 3-dimensional Sklyanin algebras associated to a point of order 2
The representation theory of a 3-dimensional Sklyanin algebra depends on its (noncommutative projective algebro-) geometric data: an elliptic curve in , and an automorphism of given by translation by a point. Indeed, by a result of Artin, Tate, and van den Bergh, we have that is module-finite over its center if and only if has finite order. In this case, all irreducible representations of are finite-dimensional and of at most dimension .
In this work, we provide an algorithm in Maple to directly compute all irreducible representations of associated to of order 2, up to equivalence. Using this algorithm, we compute and list these representations. To illustrate how the algorithm developed in this paper can be applied to other algebras, we use it to recover well-known results about irreducible representations of the skew polynomial ring .
