Thesis Title: Resolution of singularities of pairs preserving
semi-simple normal crossings
https://sites.google.com/site/franklinvp/thesis
Thesis Abstract:
A pair (X,D) of an algebraic variety X and a Weil
divisor D on it is said to be semi simple-normal crossings ("semi-snc")
at $a\in X if X is simple normal crossings at a and D is the restriction
to X of a (not necessarily reduced) hypersurface that is simple
normal crossings with respect to X. We construct a composition of
blowings-up f: X' -> X such that the transformed pair (X',D') is
everywhere semi-simple normal crossings and f is an isomorphism
over the semi-simple normal crossings points of (X,D).
