Quotients of graded quasi-Hopf algebras
Fabio Calderón, César Galindo
We classify the quasi-Hopf ideals of quasi-Hopf algebras faithfully graded by arbitrary groups. Each ideal determines a normal subgroup, recording which degrees are identified in t…

Algebraic properties of face algebras
Fabio Calderón, Chelsea Walton
Prompted an inquiry of Manin on whether a coacting Hopf-type structure and an algebra that is coacted upon share algebraic properties, we study the particular case of b…

Some interactions between Hopf Galois extensions and noncommutative rings
Fabio Calderón, Armando Reyes
In this paper, our objects of interest are Hopf Galois extensions (e.g., Hopf algebras, Galois field extensions, strongly graded algebras, crossed products, principal bundles, etc.…
