This is a second course in linear algebra, intended for honours students. There is no required textbook. The books by Roman and Halmos are both very good, cover most of the material, and are available in PDF form from the publisher for anyone on the UBC network; a lot of the material can also be found in any "abstract algebra" textbook. More details may be found in the syllabus.

- Roman, Advanced Linear Algebra, available from SpringerLink
- Halmos, Finite-dimensional Vector Spaces, available from SpringerLink
- Coleman, Calculus on Normed Vector Spaces, Chapter 1 (on SpringerLink)
- Higham, Functions of Matrices, available from SIAM
- [Your favorite author], Abstract Algebra

- The exam will take place in-class on Monday, Feburary 27. The material for it is the "constructions" chapter of the course (lectures up to and including Wendesday, Feburary 15).
- Here is a previous midterm.
- Here is this year's midterm (restricted to students in the course).

- Problem sets are due at 10:00 Vancouver time (start of class) on the date
indicated. Submission is on Canvas, and I expect typeset solutions.
- The source files for the problem sets rely on my macro file. Feel free to use it for your submissions as well.

- Solutions (only) are stored on a secure website; registered students
can access them after first
**logging on to Canvas**. - Problem set grade statistics.

- Problem Set 1 (LyX, TeX), due 18/1/2023. Solutions
- Problem Set 2, (LyX, TeX), due 25/1/2023. Solutions.
- Problem Set 3, due 3/2/2023.
- Problem Set 4, due 10/2/2023.
- Problem Set 5, (LyX, TeX), due 17/2/2023.
- Problem Set 6, (LyX, TeX), due 22/10/2019.
- Problem Set 7, due 10/3/2023.
- Problem Set 8, due 17/3/2023.
- Problem Set 9 (LyX, TeX), due 24/3/2023.
- Problem Set 10: Q2b corrected (LyX, TeX),
