Rational quiver representations: tame and wild
Fabian Januszewski
We study representation finite -rational quivers over fields of characteristic and their indecomposable representations, exploiting that all Brauer obstructions for descent…

Rational structures on quivers and a generalization of Gelfand's equivalence
Fabian Januszewski
We introduce the notion of rational structure on a quiver and associated representations to establish a coherent framework for studying quiver representations in separable field ex…
