On the surjectivity of $(T)$ -adic Galois Representations of Drinfeld $A$ -Modules of Rank 2 and 3: Density results

Narasimha Kumar, Dwipanjana Shit

Let $F_{q}$ be a finite field, and $A := F_{q} [T]$ . In this article, we give explicit criteria, involving concrete valuations, on the coefficients of the Drinfeld $…

On the surjectivity of Galois representations attached to Drinfeld $A$ -modules of rank $2$

Narasimha Kumar, Dwipanjana Shit

Let $F_{q}$ be a finite field with $q$ elements, where $q$ is a prime power and let $A := F_{q} [T]$ . By~\cite{PR09}, the adelic image of the Galois representation at…

A class of Drinfeld $A$ -modules of rank $3$ with surjective Galois representations

Narasimha Kumar, Dwipanjana Shit

Let $q = p^{e} \geq 7$ be an odd prime power, and set $A := F_{q} [T]$ . In this article, we construct an infinite two-parameter family of Drinfeld $A$ -modules of rank $3$ such…
