The multiplier ideals of an ideal in a regular local ring form a family of ideals parameterized by nonnegative rational numbers. As the rational number increases the corresponding multiplier ideal remains unchanged until at some point it gets strictly smaller. A rational number where this kind of diminishing occurs is called a jumping number of the ideal.
In this manuscript the author gives an explicit formula for the jumping numbers of a simple complete ideal in a twodimensional regular local ring. In particular, he obtains a formula for the jumping numbers of an analytically irreducible plane curve. He then shows that the jumping numbers determine the equisingularity class of the curve.
