We give some examples of, and raise some questions on, extensions of semisimple Hopf algebras.

We present examples of color Hopf algebras, i.e. Hopf algebras in color categories (braided tensor categories with braiding induced by a bicharacter on an abelian group), related with quantum doubles of pointed Hopf algebras. ...

En la primera parte de esta tesis, damos ejemplos, y planteamos algunas preguntas, sobre extensiones de álgebras de Hopf semisimples. Para esto, definimos la noción de longitud de un álgebra de Hopf, por ejemplo, que un ...

We give some examples of, and raise some questions on, extensions of semisimple Hopf algebras.

La tesis trata sobre las reglas de fusión y la resolubilidad de una categoría de fusión. En la primer parte de esta tesis se aborda el interrogante de si la condición de que una categoría de fusión sea o no resoluble está ...

This is a contribution to the classification of finite-dimensional Hopf algebras over an algebraically closed field k of characteristic 0. Concretely, we show that a finite-dimensional Hopf algebra whose Hopf coradical is ...

We show that Nichols algebras of most simple Yetter–Drinfeld modules over the projective special linear group over a finite field, corresponding to non-semisimple orbits, have infinite dimension. We spell out a new criterium ...

We prove some results on the structure of certain classes of integral fusion categories and semisimple Hopf algebras under restrictions on the set of their irreducible degrees.
