A Geometric Interpretation of Categories of Type \tilde{A} and of Morphisms in the Infinite Radical
(Journal article; Peer reviewed, 2019)We give a geometric realization of the module category of a hereditary algebra of type A~. We work with oriented arcs to define a translation quiver isomorphic to the Auslander-Reiten quiver of the module category of type ...
