Course Description
Linear transformations of finite dimensional vector spaces are studied in a semi-abstract setting. The emphasis is on topics and techniques which can be applied to other areas, e.g. bases and dimension, matrix representation, linear functionals, duality, canonical forms, vector space decomposition, inner products and spectral theory.
Any linear algebra textbook that you can read, which is sufficiently advanced. It must include the notion of a quotient space, and the proof (not just the statement) of the Jordan Canonical Form Theorem.
Course Objectives
1) To help the students prepare for the Linear Algebra Preliminary Examination.
2) To help the students formulate their goals to get the most from their graduate school training.
Grading Policy
There will be a midterm and a final examination, and the overall grade in the course will be primarily determined by the performance on these two tests. Additionally, there will be occasional quizzes and graded homework that will have some effect on the overall grade. It is a student's responsibility to attend every lecture, take notes and go over the notes before the next lecture to fully understand the material covered. If for any reason you can not attend a lecture, please get the notes from another student in the class. You should also notify the instructor of your absense. If needed, ask the instructor for help with the missed material. Some homework problems may be assigned, but not collected. It is your responsibility to do them and check with other students whether or not you got them right. If in doubt, seek help from the instructor or the recitation instructor. Recitation may have separate homework.
