Sobre distribuição e folheações holomorfas de codimensão maior do que um
(Universidade Federal de Minas GeraisUFMG, 2010-10-14)
Let w be a holomorphic LDS r-form on a complex manifold M. In the case M = Cn, we show that if ker(w) admits a trivial subbundle of rank k, then there exists a holomrphic LDS (r - k)-form n on Cn such that ! is the exterior ...
On varieties of superalgebras with graded involution and small *-graded colength
(Universidade Federal de Minas GeraisUFMG, 2017-03-06)
In this thesis, we present the extension of some classical results of PI-theory to the class of *-superalgebras, that is, superalgebras endowed with a graded involution
Crescimento polinomial das codimensões e *-codimensões
(Universidade Federal de Minas GeraisUFMG, 2013-02-26)
Let F be a field of characteristic zero. We say that the sequence of codimensions of an algebra A is polynomially bounded if there exist constants and t such that cn(A) nt for all n 1: In this dissertation, we will study ...

Fluxos Anosov R-Cobertos
(Universidade Federal de Minas GeraisUFMG, 2016-01-25)
In this study we make an introduction to Anosov systems, with special focus on Anosov ows R-covered. We present some basics of: manifolds, groups and group actions, covering spaces and fundamental group; we study the ...
Variedades de álgebras G-graduadas com involução graduada de crescimento quase polinomial
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAPrograma de Pós-Graduação em MatemáticaUFMG, 2022-02-18)
In this thesis, the main object of study is the class of the (G, ∗)-algebras, that is, algebras
graded by a group G and endowed with a graded involution ∗. Firstly, we study the algebraic structure of the (G, ∗)-algebras. ...
Superálgebras unitárias com involução graduada ou superinvolução de crescimento polinomial
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAPrograma de Pós-Graduação em MatemáticaUFMG, 2021-07-23)
If A is a superalgebra endowed with a graded involution or asuperinvolution, we say that A is a ψ-algebra. In this thesis we work with unitary ψ-algebras whose ψ-codimension sequence cψn(A) is polynomially bounded. Under ...
