Large automorphism groups compared to the $p$ -rank of algebraic curves in characteristic $p$

Massimo Giulietti, GÃ¡bor KorchmÃ¡ros, Marco Timpanella

Let $\cX$ be a (projective, geometrically irreducible, non-singular) algebraic curve of genus $\geq 2$ and positive $p$ -rank $Î³(\cX)$, defined over an algebraically closed field $\…

Algebraic curves with a large cyclic automorphism group

Arianna Dionigi, Massimo Giulietti, Marco Timpanella

The study of algebraic curves $\cX$ with numerous automorphisms in relation to their genus $g(\cX)$ is a well-established area in Algebraic Geometry. In 1995, Irokawa and Sasaki \c…
