Universal deformation rings of modules for generalized Brauer tree algebras of polynomial growth

David C. Meyer, Roberto C. Soto, Daniel J. Wackwitz

Let $k$ be an arbitrary field, $Λ$ be a $k$ -algebra and $V$ be a $Λ$ -module. When it exists, the universal deformation ring $R (Λ, V)$ of $V$ is a $k$ -algebra whose local homomorphis…

Universal deformation rings, endo-trivial modules, and semidihedral and generalized quaternion 2-groups

Frauke M. Bleher, Ted Chinburg, Roberto C. Soto

Let $k$ be a field of characteristic $p > 0$ , and let $W$ be a complete discrete valuation ring of characteristic $0$ that has $k$ as its residue field. Suppose $G$ is a finite group…

Universal Deformation Rings and Quivers of Finite Representation Type

Roberto C. Soto, Daniel J. Wackwitz

Let k be a field of arbitrary characteristic and let Q be a quiver of finite representation type. In this paper we prove that if M is an indecomposable kQ-module then the universal…
