1. Identidades polinomiais em álgebras matriciais sobre a álgebra de Grassmann / Polynomial identities in matrix algebras over the Grassmann algebra
Nesta tese estudamos a álgebra genérica de M1;1 em dois geradores sobre um corpo infinito de característica diferente de 2. Descrevemos o centro desta álgebra e provamos que este é a soma direta do corpo com um ideal nilpotente da álgebra. Como consequência mostramos que este centro contém elementos não escalares, respondendo a uma pergunta feita po

2. Identidades polinomiais graduadas de algumas àlgebras matriciais
Let K be an associative and commutative ring with 1 and let A be an associative Kalgebra with or without 1. We say that the polynomial identities of A have the Specht property if each K-algebra B satisfying all the polynomial identities of A has a finite basis for its identities. Let M2(K) be the algebra of 2 × 2 matrices over a field K. If K is a field of

3. An application of the geometric algebra to the classical mechanic : the Kustaanheimo-Stiefel transformation / Uma aplicação da algebra geometrica a mecanica classica : a transformação de Kustaanheimo-Stiefel
In this dissertation we presented the Geometric Algebra of Euclidean Space and studied some of its properties. To exemplify its applications, we studied the Kustaanheimo-Stiefel Transformation in terms of Geometric Algebra. This purpose we presented initially the KS Transformation which regularizes the Kepler motion in three dimensions by removing a singular

4. A-polynomial identities in associative algebras / A-identidades polinomiais em algebras associativas
In this PhD thesis we study polynomial identities in associative algebras. More precisely we study the A-ideIltities for several important classes of algebras. The first main result of the thesis gives a complete description of the A-identities for the Grassmann algebra over an algebraically closed field of characteristic O. In this way we give a positive an

5. Granded algebras and graded polynomial identities / Algebras graduadas e identidades polinomiais graduadas
In this work we study graded algebras and graded polynomial identities. We study two types of problems: finding the possible gradings on a given algebra, and finding a basis forthe graded identities of a given algebra. We begin with the basic definitions and results onalgebras, graded algebras, (graded) polynomial identities, etc. We give a description of th

6. Identidades polinomiais para a algebra das matrizes de ordem dois sobre corpos de caracteristica zero / Polynomial identities of the matrix algebra of order two over a field of characteristic zero
Esta dissertação introduz as primeiras noções para o estudo da teoria de álgebras que satisfazem identidades polinomiais (chamadas PI - álgebras), bem como alguns resultados importantes. Expomos alguns fatos e resultados fundamentais sobre representações dos grupos simétricos e geral linear. Estes resultados serão posteriormente utilizados para est

7. Algebraic methods in molecular science / Métodos algébricos em ciências moleculares
The vibrational spectrum of monofluoroacetylene (HCCF) and of monochloroacetylene (HCCCl) are calculated by means of algebraic techniques under the hypothesis that they result from a U(4) symmetry through the chain U(4) symmetry through the chain U(4) ⊃ O(4) ⊃ O(3). The results are compared with the 170 experimentally available vibrational lines

8. Lie algebras and classical partition identities
In this paper we interpret Macdonald's unspecialized identities as multivariable vector partition theorems and we relate the well-known Rogers—Ramanujan partition identities to the Weyl—Kac character formula for an infinite-dimensional Euclidean generalized Cartan matrix Lie algebra.

10. Modular invariant representations of infinite-dimensional Lie algebras and superalgebras
In this paper, we launch a program to describe and classify modular invariant representations of infinite-dimensional Lie algebras and superalgebras. We prove a character formula for a large class of highest weight representations L(λ) of a Kac-Moody algebra [unk] with a symmetrizable Cartan matrix, generalizing the Weyl-Kac character formula [Kac, V.
