El trabajo se centra en el estudio de la categoría de álgebras diferenciales graduadas de Frobenius. Esta categoría combina los conceptos de álgebras de Frobenius y de álgebras diferenciales graduadas. A los objetos de ...

We introduce a new filtration on Hopf algebras, the standard filtration, generalizing the coradical filtration. Its zeroth term, called the Hopf coradical, is the subalgebra generated by the coradical. We give a structure ...

Let k be an algebraically closed field of characteristic zero. In this paper, we prove that fusion categories of Frobenius–Perron dimensions 84 and 90 are of Frobenius type. Combining this with previous results in the ...

In this work I study solutions of Second Order Linear Diferential Equations with non-constant coefficients. In order to solve these kinds of problems I use power series methods, in particular the Sucessive Differentiations ...

Sea A = {a1, a2, . . . , ak} un conjunto de enteros positivos primos relativos entre sí. Dado un entero positivo N, se dice que N es representable por A si existen enteros no negativos x1, x2, . . . , xk tales que N = Pk ...
