## 1 Description

This is a one-semester course in linear algebra and vector spaces. An emphasis is made on the coordinate free analysis. The course mimics in some ways a modern algebra course.

## 5 Notes

The content came from this complete set of handwritten lectures.

Texts:

The following topics weren't addressed enough:

- quotients, products, etc,
- infinite-dimensional spaces,
- inner products spaces,
- dual spaces,
- eigenvalues and eigenvectors,

or not at all:

- multilinear algebra;
- tensor product;
- vector spaces over general fields, modules.

All are required for serious applications of linear algebra.
