Course overview and goals

The main topics of this course are the basic concepts and properties related to (commutative) rings, ideals, and modules over them. After reviewing some of the basics on (commutative) rings, ideals, and residue rings mod out by ideals, students will learn the concept of modules over a ring systematically, together with many of the related concepts including submodules, residue modules, linear mappings, homomorphism theorem, direct sums and direct products, exact sequences, Hom modules, free modules, etc. This will be followed by a study on basic topics on tensor products of modules, the right exactness of tensor products, and further related concepts (e.g., flatness). This course is followed by "Algebra II."

Rings, ideals, and modules over rings are among the most basic concepts in advanced algebra, which admits wide applications. However, its abstractness would cause several difficulties for newcomers. Students in this course will attempt to solidify these concepts in their minds by becoming familiar with these kinds of abstract concepts through rational integer rings and polynomial rings which are typical examples of (commutative) rings.

Course description and aims

By the end of this course, students will be able to:
1) Understand the notions of (commutative) rings and modules over rings.
2) Understand tensor products and make use of them correctly.
3) Understand localization and make use of them correctly.
