Compatible Bases and Actuator Scheduling
Dawid E. Kędzierski, Piotr Krasoń
We study a constrained basis-selection problem for an ordered block matrix The successive tail matrices determine a nested family of column spaces, a…
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 -composition factors. They form a h…
Weil-Barsotti formula for -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 and were Anderson \tm modules ov…
On for Drinfeld modules
D. E. Kedzierski, P. Krasoń
Let be the polynomial ring over a finite field and let and be Drinfeld modules. In this paper we consider the group ${\mathrm{Ext}}…
Modules attached to extension bundles
Dawid Kędzierski, Hagen Meltzer
In this article we study modules over wild canonical algebras which correspond to extension bundles [9] over weighted projective lines. We prove that all modules attached to extens…
Matrix factorizations for domestic triangle singularities
Dawid Edmund Kędzierski, Helmut Lenzing, Hagen Meltzer
Working over an algebraically closed field of any characteristic, we determine the matrix factorizations for the --- suitably graded --- triangle singularities …
