Ideal classes of orders in quaternion algebras

Abstract

We provide an algorithm that, given any order OO in a quaternion algebra over a global field, computes representatives of all right equivalence classes of right OO-ideals, including the non-invertible ones. The theory is developed for a more general kind of algebras.
