Superpotentials and Quiver Algebras for Semisimple Hopf Actions

Abstract We consider the action of a semisimple Hopf algebra H on an m -Koszul Artin–Schelter regular A . Such is derivation-quotient for some twisted superpotential w , and we show that homological determinant can be easily calculated using Using this, smash product # also algebra, use this to explicitly determine quiver Λ which Morita equivalent, generalising result Bocklandt–Schedler–Wemyss. how used whether Auslander map isomorphism. compute number examples, several results quantum Kleinian singularities studied by Chan–Kirkman–Walton–Zhang follow our techniques.
