  • Sep 3: Welcome to the course! No tutorial lecture in the 1st week. Here is the course outline: [Download file]
  • Sep 21: 1. Midterm 1 will be held on October 9, 2020 (Friday) and Midterm 2 will be held on November 6, 2020 (Friday). Please mark it down on your calendar. Midterm 1 will be held about three weeks from now. 2. Midterm examinations will be conducted online using "Blackboard" as a "take-home exam" with a 24 hours limit. For midterm 1, the examination question will be available on October 9, 2020 at 10:00am and the deadline for submission (via "Blackboard") is October 10, 2020 at 10:00am. It is expected that the paper can be finished within 3 hours. As such, the 24-hour limit should allow enough flexibility. 3. Midterm 1 will cover materials taught from Week 1 to Week 4.
  • Oct 6: Covers of Midterm One are updated as the only Chapter 1 of the textbook, that is Topic 1 to Topic 4 of the course lectures.

Course Description

This course is a continuation of Linear Algebra I (MATH 1030). It is a second course on linear algebra and will cover basic concepts of abstract vector spaces, linear transformations, eigenvalues and eigenvectors, diagonalizability, operators on inner product spaces, orthogonality and Gram-Schmidt process, adjoint, normal and self-adjoint operators, spectral theorems, and if time permits, quadratic forms and Jordan canonical forms. More emphasis will be put on the theoretical understanding of basic concepts in linear algebra.
