RESUMO
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 showed in [16] that under certain conditions, semi-stable representations of a quiver are parametrized by an irreducible, normal projective algebraic variety. We show that we have the same results for twisted representations. Our main and original result provides an equivalence between the category of twisted representations of a quiver Q, RepMQ, and the category of representations of a quiver Q, Rep Q, where Q depends on Q and on the twisting factors. With this equivalence we developed the existing theory of representations of quivers for twisted representations, we rewrote classical results like Gabriels theorem and Kacs theorem for the category of twisted representations and found a relation between RepQ and RepMQ.
