Computing special values of partial zeta functions
We discuss computation of the special values of partial zeta functions
associated to totally real number fields. The main tool is the \emph{Eisenstein
cocycle} , a group cocycle for ; the special values are
computed as periods of , and are expressed in terms of generalized
Dedekind sums. We conclude with some numerical examples for cubic and quartic
fields of small discriminant.Comment: 10 p
Explicit Resolutions of Cubic Cusp Singularities
Resolutions of cusp singularities are crucial to many techniques in computational number theory, and therefore finding explicit resolutions of these singularities has been the focus of a great deal of research. This paper presents an implementation of a sequence of algorithms leading to explicit resolutions of cusp singularities arising from totally real cubic number fields. As an example, the implementation is used to compute values of partial seta functions associated to these cusps
