Fixed Points on Asymmetric Riemann Surfaces

Fixed point free involutions on Riemann surfaces

Involutions without fixed points on hyperbolic closed Riemann surface are discussed. Notably, the following question is answered: for τ such an involution on a surface (S, d), can a point p be chosen so that d(p, τ(p)) is bounded by a constant dependent solely on the genus of S? This is proved to be true for even genus and false otherwise. Furthermore, the sharp constant is given in genus 2.

Computing on Riemann Surfaces

These notes are a review on computational methods that allow us to use computers as a tool in the research of Riemann surfaces, algebraic curves and Jacobian varieties. It is well known that compact Riemann surfaces, projective algebraiccurves and Jacobian varieties are only diierent views to the same object, i.e., these categories are equivalent. We want to be able to put our hands on this equ...

Coalescence on Riemann Surfaces

We consider coalescing fermions on a Riemann Surface and derive generalized determinant formulas, complementing some results of 3].

Uniform Approximation on Riemann Surfaces

This thesis consists of three contributions to the theory of complex approximation on Riemann surfaces. It is known that if E is a closed subset of an open Riemann surface R and f is a holomorphic function on a neighbourhood of E, then it is “usually” not possible to approximate f uniformly by functions holomorphic on all of R. In Chapter 2, we show, however, that for every open Riemann surface...
