1. Álgebras bisseriais especiais / Special biserial algebras
Special biserial algebras are a class of algebras that appear in many contexts. Butler and Ringel [6] made a description of indecomposable modules and irreducible morphisms of algebras string, a subclass of special biserial algebras. We show that special biserial algebras which are not string, have only one module projective-injective indecomposable for each

2. Complexidade de Módulos / Complexity of Modules
A complexidade de um módulo M, sobre uma álgebra de dimensão finita R, é a medida do crescimento da dimensão de suas sizigias. No nosso trabalho, estudamos esse conceito, nos concentrando muito mais no caso das álgebras autoinjetiva. Relacionamos esse crescimento com o comportamento da componente do carcás de Auslander-Reiten, a qual o módulo M perte

3. Root system and representation of quivers / Sistema de raizes e representações de quivers
In this work, we define quivers and their representations, and discuss how the category of modules over an arbitrary connected associative algebra can be associated to the category of representations of a quiver. We also study the root system of the Cartan quadratic form associated to a quiver, which is bijective with the set of dimension vectors for which a

4. Representações torcidas de Quivers / Twisted representations of quivers
The main goal of this thesis is to introduce for the category of twisted representations of a quiver Q the definitions and results one already knows for categories of representations of quivers. The concept of twisted representations was introduced by Gothen and King in [11] to study problems concerning vector bundles over algebraic varieties. King also show

5. Geometric invariant theory and representations of quivers / Teoria geometrica dos invariantes e representações de quivers
This thesis is divided into two parts. ln the first part we present the main ideas and tools of Geometric lnvariant Theory, which is concerned with the following problem: ls it possible to give an algebraic structure to the quotient of an algebraic variety by the action of an algebraic group? Qne of the most important results says that an algebraic quotient
