A note on extending Hopf actions to rings of quotients of module algebrasChristian LompCentro de Matemática da Universidade do Porto, R. Campo Alegre 687, 4169007 Porto, PortugalAbstract: Given a Hopf algebra $H$ and an $H$module algebra $A$ it is often important to be able to extend the $H$action from $A$ to a localisation of $A$. In this paper we discuss sufficient conditions to extend Hopf actions as well as to characterise those localisations where the action can be extended. Our particular interest lies in the maximal ring of quotients of $A$. Full text of the article:
