Reconstruction Algebras of Type A

Abstract

We introduce a new class of algebras, called reconstruction algebras, and present some of their basic properties. These non-commutative rings dictate in every way the process of resolving the Cohen-Macaulay singularities C2/G where G is a finite small cyclic subgroup of GL(2,C).
