The type- \(A\) Kleinian singularities are the surfaces of the form \(C^{2} / G\) where \(G\) is a finite cyclic subgroup of \(S L_{2}(\mathbb{C})\). The standard noncommutative analog is the fixed ring of the Weyl algebra \(A_{1}(\mathbb{C})\) under the induced action of \(G\). These fixed rings ar
