Maximal Subcovers of the Skabelund Curve: Uniqueness via Genus and Automorphism Groups

Gilberto B. Almeida Filho, Saeed Tafazolian, Stéfani C. Vieira

We establish a rigidity phenomenon for a family of intermediate covers of the Skabelund curve over ${\mathbb{F}}_{q^4}$. The Skabelund curve, introduced by D.~Skabelund as a cyclic c…
