Jumping Numbers on Algebraic Surfaces with Rational Singularities

  title={Jumping Numbers on Algebraic Surfaces with Rational Singularities},
  author={Kevin Tucker},
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 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… CONTINUE READING
