Endomorphism Rings and Isogenies Classes for Drinfeld Modules of Rank 2 Over Finite Fields

Mohamed Ahmed Mohamed Saadbouh

Let $\Phi$ be a Drinfeld ${\mathbf{F}}_q[T]$-module of rank 2, over a finite field $L$, a finite extension of $n$ degrees of a finite field with $q$ elements ${\mathbf{F}}_q$. Let $m$…
