Academic Program

It is expected that students entering the program have an adequate preparation in both physics and mathematics. The normal requirement is either a master's degree or the equivalent of a Canadian honours degree in one of the two disciplines, with strong preparation in the other. The following is a list of subjects with which the incoming student is assumed to have familiarity at this level.

  • Physics: classical mechanics; statistical mechanics; classical electrodynamics; quantum mechanics; relativity.
  • Mathematics: Real analysis, functional analysis; complex variables; differential equations; introductory group theory and algebra; measure theory.

Besides the specific courses offered this year, the following general framework of courses is recommended to students doing their degrees within this program. The needs and background of each individual student will determine which of these courses is required; the choice and timing should be determined in consultation with the student's thesis advisor. In any particular year, these courses might be offered at only one of the participating universities, but the titles and course numbers are listed in order to facilitate cross registration. In the following, an asterisk (*) signifies a (Master's level) course that is obligatory for all students in the programme, and (*m) signifies a course that is obligatory for students who have not already completed the equivalent at a level equivalent to an honours level undergraduate degree. The following notation is used to distinguish the level and frequency of courses offered:

  • A= course offered at least annually at one of the participating universities.
  • B= course offered every second year at one of the participating universities.
  • C= course offered according to demand at one of the participating universities.
  • b= basic level (Master's level)
  • i= intermediate level (Master's or doctoral)
  • s= specialized course (Master's or doctoral)

Fall

Topics in Algebra: Lie Algebras and Lie Groups

The course aims at introducing the notion of Lie group  and Lie algebra, with focus on concrete matrix representations. We will start with a minimalistic review of necessary notions of differential geometry  and move progressively into the theory of the classification of semisimple Lie algebras (and groups). We will also discuss some representation theory. 

After the introduction, the main topics  we aim at covering are: Connection between Lie groups and Lie Algebras (Baker-Cambpell-Hausdorff); general theory of Lie algebras; nilpotent, solvable and semisimple algebras; Classical simple Lie  groups and  algebras; classification (Dynkin diagrams); representation theory (Weyl theorem, weight spaces, irreducible reps, characters); integration over groups and Haar measure.

 We will keep the prerequisites to a minimum.

Topics in Analysis: Entropic Information Theory

The course concerns modern entropic information theory centred around coding algorithms. It will follow the book “The Ergodic Theory of Discrete Sample Paths” by Paul C. Shields AMS Graduate Studies in Mathematics, Vol 13, 1996, with digressions concerning more recent developments. The course will continue with a research seminar in the Winter 2021. Various research opportunities (post-doctoral, PhD, masters, and undergraduate level) related to the material of the course and the seminar will be available starting Summer 2021. Besides the students in mathematics and statistics, this course might be of interest to mathematically inclined students in electrical engineering and computer science. Staring with the seminal work of Shannon, most of the central topics of the course originated in the field of electrical engineering/information transmission.
