## Recommended Prerequisites

Linear Algebra and Analytic Geometry I, II;

Groups and Symmetries;

Fields and Algebraic Equations.

## Teaching Methods

The lessons are mixed in nature, providing students with an opportunity to learn using concrete cases. The concepts are preceded by persistent exemplification. Sometimes the lessons take a slightly opposite turn, beginning with a discussion about an abstract definition and then providing the consequences and the concrete applications of that definition. A substantial part of the lessons is put aside for the solution of problems, where students are encouraged to work and discuss as a group.

## Learning Outcomes

Introduction to abstract concepts in commutative rings theory. Development of the capacity for abstraction and argumentation. Acknowledgment of the fundamental structures of Mathematics, as well as their origin and their concrete use. Study of the most important proprieties related to the concepts of ideals and modules, and their application to geometry.

Generic competences:

Capacity for generalization and abstraction;
