Linear Algebra II
Welcome to Linear Algebra II !
You are registered for MAS 4107, CRN: 12196 (3 credits). We meet Mondays and Wednesdays, 4:00 - 5:20 p.m. in Physical Sciences 112.
Linear algebra is the branch of mathematics which has developed from a theoretical study of the problem of solving systems of linear equations. This problem is one of the oldest in mathematics and is still of fundamental importance in other areas in mathematics and for applications to science and engineering.
The abstract approach in linear algebra and the rich variety of concepts arising from vector spaces relate to --- and help understand --- topics and results in modern pure mathematics.
Of course, linear algebra is essential in applications as well; its methods apply to calculus, differential equations, coding and cryptography. Linear algebra techniques, in particular visualization, play an important role in modern physics, engineering, computer animation and the social sciences (particularly economics).
Prerequisite
None in particular, but mathematical maturity (proof writing) is expected.
Textbook and Topics
We will use the book by Sheldon Axler, Linear Algebra Done Right, fourth edition, Springer Nature, ISBN 978-3031410253.
We are going to cover the following chapters:
- Brief review of vector spaces and their basic properties (Chapter 1, 2 weeks)
- Linear independence, span, basis and dimension for finite-dimensional vector spaces (Chapter 2, 3 weeks)
- Linear maps, null space and range (Chapter 3, 6 weeks)
- Invariant subspaces, eigenvectors and eigenvalues (Chapter 5, 3 weeks)
- The Jordan Normal Form Theorem for linear operators on a finite dimensional complex vector space. (Chapter 8, as time permits)
Objectives
- Work with abstract definitions and theorems in the familiar setup of vectors and matrices
- Revisit and understand algorithms to compute bases, eigenvalues, generalized eigenvectors etc.
- Pracise proof writing to ascertain basic results in linear algebra
- Seek examples to show that hypotheses in theorems are necessary

Credit Homework: I will assign homework problems every week. The problems will not be graded, but some may show up on a quiz. Please bookmark the link:Homework Problems. Quizzes: We will have a quiz every Wednesday; the best eleven quizzes count for 50 % of the grade.
Presentation: One presentation during class will count for 10 % of the grade. The last day for the presentation is April 8. Unless there are volunteers, I will assign presentations for the next class meeting (at random among all registered students who have not given a talk yet).
Final Exam: The final exam is comprehensive and will count for 40 % of your grade. It is scheduled for Monday, April 29, 4:00 - 6:30pm in our classroom. Please bring a picture id (Owl card or drivers licence)!
