%0 Journal Article %T Jumping Numbers on Algebraic Surfaces with Rational Singularities %A Kevin Tucker %J Mathematics %D 2008 %I arXiv %X In this article, we study the jumping numbers of an ideal in the local ring at rational singularity on a complex algebraic surface. By understanding the contributions of reduced divisors on a fixed resolution, we are able to present an algorithm for finding of the jumping numbers of the ideal. This shows, in particular, how to compute the jumping numbers of a plane curve from the numerical data of its minimal resolution. In addition, the jumping numbers of the maximal ideal at the singular point in a Du Val or toric surface singularity are computed, and applications to the smooth case are explored. %U http://arxiv.org/abs/0801.0734v2
