Cataloque Contents: Rings, ideals, isomorphism theorems, group rings,
localization, factor rings. Modules, submodules, direct products, factor
modules. Homomorphisms, classical isomorphism theorems. The endomorphism ring
of a module. Free modules, free groups. Tensor product of modules. Finitely
generated modules over a principal ideal domain.
Grading will be based on the exams. There will be only one make
-up exam for any of the exams missed. It will be after the final exam and you
should have your instructors permission to be able to take it.
Description of the course
As the title suggests this course consists of two parts, rings
and modules. Rings will be expanded version of what you have seen in
Math 367, and also Math 116 with the addition of localization. Since my interest is in modules over group algebras
I will bring in examples from those. We will spend two thirds of the semster for
rings (about 8-9 weeks).
Modules will be new to you. They are generalizations of vector spaces. In spirit
module theory is a generalization of linear algebra.
(about 6 weeks).
I. Rings, main titles are:
Rings, ideals, homorphism of rings, group algebras . II. Modules,
main titles are: Modules, free modules, quotient modules, modules over a
PID, modules over group algebras (if time permits).
We will use the
following book.
Textbook: Introduction to Rings
and Modules, Second Revised Edition, by C. Musili, Narosa Publishing House,
1994
I will follow the book section by section. It has 6 chapters,
we must cover the first five chapters about 150 pages in total.
Chapters 1—4 are on rings, only Chapter 5 is on modules so I
will expand it a little bit.
This course is to provide
the background for students who are willing to learn more about rings
which are the common mathematical
structures occuring everywhere J! It is good for everyone J but especially for
students who are
planning to study
any algebra related topics such
as algebraic topology, algebraic geometry.
