On Riemann surfaces of genus $g$ with $4g-4$ automorphisms

Algebraic Geometry 2021-05-04 v1

Abstract

In this article we study compact Riemann surfaces with a non-large group of automorphisms of maximal order; namely, compact Riemann surfaces of genus gg with a group of automorphisms of order 4g4.4g-4. Under the assumption that g1g-1 is prime, we provide a complete classification of them and determine isogeny decompositions of the corresponding Jacobian varieties.
