Abstract
One of the most important tools in singularity theory is the notion of a resolution of the singularity. If (X,0) is the germ of a singular variety, then a resolution of (X,0) is a smooth germ (Y,E) together with a proper map p from (Y,E) onto (X,0), such that p restricts to an isomorphism (Y-E)to (X-0)$. There are several ways to obtain a resolution. The classical way is through repeated …
