For any finite-dimensional Hopf algebra H we construct a group homomorphism BiGal (H) → BrPic(Rep(H)), from the group of equivalence classes of H-biGalois objects to the group of equivalence classes of invertible exact ...

There are different notions of computation, the most popular being monads, applicative functors, and arrows. In this article, we show that these three notions can be seen as instances of a unifying abstract concept: monoids ...

En el presente trabajo se busca dar ejemplos explícitos de categorías tensoriales, usando la maquinaria de las representaciones de tales categorías y las bicategorías; ambos conceptos recientemente introducidos en el ámbito ...

We describe (braided-) commutative algebras with non-degenerate multiplicative form in certain braided monoidal categories, corresponding to abelian metric Lie algebras (so-called Drinfeld categories). We also describe ...

Recent work by the authors equips Petri occurrence nets (PN) with probability distributions which fully replace nondeterminism. To avoid the so-called confusion problem, the construction imposes additional causal dependencies ...

La tesis trata sobre las álgebras de Hopf semisimples y las categorías tensoriales asociadas. En la primera parte de la tesis mostramos dos familias de ejemplos de álgebras de Hopf semisimples que no son simples, pero que ...
