A subvariety Z ? X of codimension i is algebraically coisotropic if the distribution above is algebraically integrable, by which we mean that there exists a rational map ? : Z (i) The codimension of Z is equal to i and (the smooth locus of ) Z is algebraically coisotropic (see Denition 0.6).

In this paper we propose the concept of formal desingularizations as a substitute for the resolution of algebraic varieties. Though a usual resolution of algebraic varieties provides more information on the structure of singularities there is evidence that the weaker concept is enough for many
In algebraic geometry, the problem of resolution of singularities asks whether every algebraic variety V has a resolution, a non-singular variety W with a proper birational map W>V. For varieties over
