Large orders of automorphisms of smooth curves in
Taro Hayashi, Keika Shimahara
For , we calculate the orders of automorphisms of smooth curves with bidegree in the product $\pp$ of the projective line . We identify smooth curve…

Subgroups of the Projective Linear Group Realized by wild Galois Points
Taro Hayashi, Kashu Ito, Atsuya Nakajima +1
We work over an algebraically closed field of positive characteristic. This paper investigates linear representations of Galois groups arising from wild Galois points on projective…

Persistence of Galois property of hypersurfaces over algebraic integers across other characteristics
Taro Hayashi, Kento Otsuka, Keika Shimahara +1
In this paper, we investigate hypersurfaces defined over a ring of algebraic integers, and show that if the projection from a point induces a Galois extension over either a number…
