  2. 1. Cyclic Trigonal Riemann Surfaces of Genus 4

    Author : Daniel Ying; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Riemann surface; trigonal morphism; Accola; genus 4; MATHEMATICS; MATEMATIK;

    Abstract : A closed Riemann surface which can be realized as a 3-sheeted covering of the Riemann sphere is called trigonal, and such a covering is called a trigonal morphism. Accola showed that the trigonal morphism is unique for Riemann surfaces of genus g ≥ 5. This thesis will characterize the Riemann surfaces of genus 4 wiht non-unique trigonal morphism. READ MORE
