Hsiang-Pati coordinates
Edward Bierestone (Toronto)
Abstract:
Recent progress on the problems of monomialization of differential
forms or of a Fubini-Study metric on a singular complex variety. The
problems were originally motivated by possible applications to L_2 and
intersection cohomology. Earlier results of Hsiang-Pati and
Pardon-Stern give solutions for surfaces with isolated singularities.
Recent results include: (1) Equivalence of Hsiang-Pati parametrization
and principalization of logarithmic Fitting ideals. (2) Solution of
the main problems in the general 3-dimensional case.
