General Information Syllabus HW Assignments

Syllabus

The main focus of the course will be modules (projective, injective, free, torsion), applications to linear algebra including canonical forms, direct products, tensor products, coproducts, and categorical characterization in terms of universal mapping properites. We will also do some group theory towards the end of the course. This will involve chapters $10-12$ and $4 - 5$ of Dummit and Foote's text Abstract Algebra as well as supplementary material. Below is a tentative syllabus; the weekly syllabus contained on the Homework Assignments page will always be accurate.
