Abstract

Suppose that RR is a local domain essentially of finite type over a field of characteristic 0, and ν\nu a valuation of the quotient field of RR which dominates RR. The rank of such a valuation often increases upon extending the valuation to a valuation dominating R^\hat R, the completion of RR. When the rank of ν\nu is 1, Cutkosky and Ghezzi handle this phenomenon by resolving the prime ideal of infinite value, but give an example showing that when the rank is greater than 1, there is no natural ideal in R^\hat R that leads to this obstruction. We extend their result on the resolution of prime ideals of infinite value to valuations of arbitrary rank.
