Principal assistant:

Harmeet Singh

Important Notes:

  • The course will be conducted online, i.e. all the lectures will be pre-recorded and the videos will be made available to the students on Moodle at the beginning of each week.
  • Starting on 9 September, students must use the following Moodle page to enrol for the course. This will allow them to view all the information they need for the class, and receive important communications regarding the course by e-mail . The students must subsequently register for the course on IS-Academia between 14 September and 25 September. Failing to do so, they will be automatically removed from the Moodle list.
  • If you have any difficulty registering for the course on Moodle, or for any other questions regarding the logistics of the course, please contact the principle assistant Harmeet Singh by e-mail.
  • Course


    • Linear Algebra and its Applications, D.C. Lay, Pearson (5th edition).
    Week by week schedule of the sections of the book to be covered will be provided below as the course progresses.

    Note: All students are required to have access to a recent edition of the D.C. Lay book mentioned above. The course will follow the precise numbering of the 5th edition (which is not very different from the 4th). Any other edition would also suffice. In case of discrepancy, follow the topics by title.
