The minimal polygon for computing Z(,f)(0,b) over a real quadratic base field

Daniel James Carter, University of Massachusetts Amherst

Abstract

In this thesis we develop an algorithm for determining the convex hull of a sector in a planar lattice. This algorithm will be used to construct a minimal polygon within a sector of the embedding of a fractional ideal of a real quadratic field. It has been shown that the smoothed partial zeta-function $Z\sb{f}(s,b)$, when evaluated at $s=0$, can be calculated directly from this embedding. The minimal polygon will not only calculate $Z\sb{f}(0,b)$ efficiently, but also provide a geometric interpretation of the computational cost of calculating this value.
