Objetivos:
O Objetivo é introduzir o estudo de retas projetivas com peso, e a teoria de feixes sobre a mesma, os feixes inclinantes e os complexos inclinantes na categoria derivada, bem como a ação do grupo de tranças sobre esse objetos.
Objectives:
The objective is to introduce the study of the weighted projective lines and the category of sheaves over it, as well the study of the derived category.
Justificativa:
O estudo desses objetos tem uma importância muito grande na teoria de representações. Essa disciplina representa uma disciplina avançada para os alunos de Álgebra.
Rationale:
These topics represent an important aspect of the representation theory. This is an advanced course which will be important for the students in Algebra.
