TitleFormal desingularization of surfaces: The Jung method revisited
Author(s) Thomas Becker
TypeArticle in Journal
AbstractIn this paper we propose the concept of formal desingularizations as a substitute for the resolution of algebraic varieties. Though a usual resolution of algebraic varieties provides more information on the structure of singularities there is evidence that the weaker concept is enough for many computational purposes. We give a detailed study of the Jung method and show how it facilitates an efficient computation of formal desingularizations for projective surfaces over a field of characteristic zero, not necessarily algebraically closed. The paper includes a constructive extension of the Theorem of Jung–Abhyankar, a generalization of Duval’s Theorem on rational Puiseux parametrizations to the multivariate case and a detailed description of a system for multivariate algebraic power series computations.
