Computing Invariants of Artin-Schreier Curves
Juanita Duque-Rosero, Elisa Lorenzo García, Beth Malmskog +1
We present an algorithmic framework for computing generators for the ring of invariants of an Artin-Schreier curve. We give explicit invariants for almost all Artin-Schreier curves…

Computing submodules of points of general Drinfeld modules over finite fields
Antoine Leudière, Renate Scheidler
We present an algorithm for computing the structure of any submodule of the module of points of a Drinfeld -module over a finite field, where is a function ring over $\mathb…

The Spine of a Supersingular -Isogeny graph
Taha Hedayat, Sarah Arpin, Renate Scheidler
Supersingular elliptic curve -isogeny graphs over finite fields offer a setting for a number of quantum-resistant cryptographic protocols. The security analysis of these sche…
