Contrasting the tame case, we give an example of a simple quiver of wild representation type, where we realize every possible Brauer obstruction of a given Galois extension $L/K$ in the category of quiver representations over $L$.","lang":"eng"}],"external_id":{"arxiv":["2510.00924"]},"date_created":"2025-11-17T13:53:37Z","type":"preprint"}
