Categorias de feixes, álgebras de incidência e equivalências derivadas
(Universidade Federal de Minas GeraisUFMG, 2019-04-16)
A finite partially ordered set (poset) X carries a natural structure of a topological space, so we can consider the category of sheaves over X with values in an abelian category A which can be identified with the category ...
The geometry of quadratic polynomial differential systems with a finite and an infinite Saddle-Node (C)
(World Scientific PublishingSingapore, 2015-03)
Planar quadratic differential systems occur in many areas of applied mathematics. Although more than one thousand papers have been written on these systems, a complete understanding of this family is still missing. Classical ...

q-Analog of the gap equation for cuprates
(Elsevier B.V., 2012-03-01)
The q-deformed algebraic method based on the extension of the number concept as proposed by Gauss [1] is used to obtain a q-analog to the gap equation for the cuprates using a tight-binding model. The conventional s-wave ...

On conjugacy of Cartan subalgebras in extended affine Lie algebras
(Academic Press Inc Elsevier Science, 2016-02)
That finite-dimensional simple Lie algebras over the complex numbers can be classified by means of purely combinatorial and geometric objects such as Coxeter-Dynkin diagrams and indecomposable irreducible root systems, is ...
