Homological Methods in the Generalization of Drinfeld Modules

Dawid E. Kędzierski, Piotr Krasoń

We introduce and study a natural class of Anderson t- modules, called triangular t-modules, characterized by having Drinfeld modules as their $τ$ -composition factors. They form a h…

Weil-Barsotti formula for $T$ -modules

Dawid E. Kędzierski, Piotr Krasoń

In the work of M. A. Papanikolas and N. Ramachandran [A Weil-Barsotti formula for Drinfeld modules, Journal of Number Theory 98, (2003), 407-431] the Weil-Barsotti formula for the…

Algorithms for determination of t-module structures on some extension groups

Filip Głoch, Dawid E. Kędzierski, Piotr Krasoń

In \cite{kk04} the second and third author extended the methods of \cite{pr} and determined the \tm module structure on $\Ext^1(Φ,Ψ)$ where $Φ$ and $Ψ$ were Anderson \tm modules ov…

On $Ext^{1}$ for Drinfeld modules

D. E. Kedzierski, P. Krasoń

Let $A = F_{q} [t]$ be the polynomial ring over a finite field $F_{q}$ and let $ϕ$ and $ψ$ be $A -$ Drinfeld modules. In this paper we consider the group ${\mathrm{Ext}}…
