Course description and aims

The main topics of this course are more advanced concepts and properties of (commutative) rings and their ideals, as well as the concepts and properties of modules over (Noetherian) rings. The instructor in this course will first explain localization of (commutative) rings, and several fundamental operations for ideals, then explain primary decomposition of ideals. Next, the instructor will introduce the concept of Noetherian rings, explain several of their properties, and furthermore Hilbert's basis theorem. Finally, the instructor will introduce the concept of modules over (Noetherian) rings, explaining in particular the structure theorem of finitely generated modules over principal ideal domains. Then students will learn as an application about the existence of Jordan normal forms that are very useful in linear algebra, as well as how to calculate them. In each class, students will complete exercises related to the course content. This course follows ""Algebra 1"".
The theory of modules over rings expands and develops the theory of vector spaces and linear mapping theory learned in linear algebra to more general cases. In addition, the concept of (Noetherian) rings and modules over them is a fundamental concept of algebra, and a very wide range of applications extending over both algebra and mathematics as a whole. The goal of this course is for students to become familiar with these concepts, firmly grasp their basic properties, and learn to use them correctly.

Student learning outcomes

By the end of this course, students will be able to:
1) Understand the notion of localization of (commutative) rings, and make use of fundamental operations for ideals correctly.
2) Understand the primary decomposition of ideals, and make use of it.
3) Explain the definition and some of the basic properties of a Noetherian ring.
4) Understand the notion of modules over a (Noetherian) ring and some of their properties.
5) Understand and make use of the structure theorem for finitely generated modules over a principal ideal domain correctly.
