ABSTRACT
Ever since the dawn of non-commutative algebraic geometry in the mid seventies, see for example the work of P. Cohn [11], J. Golan [17], C. Procesi [38], F. Van Oystaeyen and A. Verschoren [47],[48], it has been ringtheorists’ hope that this theory may one day be relevant to commutative geometry, in particular to the study of singularities and their resolutions.
