Abstract

Consider a projective variety XPnX \subset \mathbb{P}^n (over an algebraically closed field of characteristic zero), together with a (reduced) simple normal crossings divisor EPnE \subset \mathbb{P}^n, where the degrees of both XX and EE are at most dd. We show there is a pair (n,d)(n',d') which can be explicitly computed in terms of (n,d)(n,d), such that (X,E)(X,E) has a log resolution of singularities (X,E)(X',E'), where (X,E)(X',E') can be embedded in Pn\mathbb{P}^{n'} and both XX' and EE' have degrees at most dd' in Pn\mathbb{P}^{n'}.
