A birational embedding with two Galois points for quotient curves

S Fukasawa, K Higashine - Journal of Pure and Applied Algebra, 2021 - Elsevier
A criterion for the existence of a birational embedding with two Galois points for quotient
curves is presented. We apply our criterion to several curves, for example, some cyclic …

Weierstrass semigroups on the Skabelund maximal curve

In this paper, explicit equations for algebraic curves with genus 4, 5, and 10 already studied
in characteristic zero, are analyzed in positive characteristic p. We show that these curves …

[HTML][HTML] Classification of all Galois subcovers of the Skabelund maximal curves

P Beelen, L Landi, M Montanucci - Journal of Number Theory, 2023 - Elsevier
In 2017 Skabelund constructed two new examples of maximal curves S˜ q and R˜ q as
covers of the Suzuki and Ree curves, respectively. The resulting Skabelund curves are …
