Semigrupos e monoides algébricos: uma aplicação na teoria da computação
(Blumenau, SC, 2021-05-07)
O objetivo deste trabalho é aplicar a teoria de semigrupos e monoides
algébricos à linguagens e autômatos da teoria da computação. Para
tanto, primeiramente é feito um estudo sobre semigrupos e monoides algébricos, ...
Notions of computation as monoids
(Cambridge University Press, 2017-10)
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 ...

Galois orders in skew monoid rings
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
We introduce a new class of noncommutative rings - Galois orders, realized as certain subrings of invariants in skew semigroup rings, and develop their structure theory. The class of Calms orders generalizes classical ...
Categorías tensoriales : representaciones y extensiones
(2014-07)
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 ...
Invertible bimodule categories over the representation category of a Hopf algebra
(2014-02-12)
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 ...
