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)

A Survey of Modern Geometric Structures and Challenges (non-credited course)

Target Audience: Second-degree mathematics/physics undergraduates - PhD students

This course introduces several of the principal geometric structures relevant to the description of classical mechanics and classical field theories. Basic knowledge of differential geometry is assumed, including vector and principal bundles, Poincaré's lemma, and calculus on manifolds. Half of the course delves into standard topics in symplectic, Poisson, and Dirac geometry, while the latter segments focus on structures pertinent to contemporary research problems. These include contact and multisymplectic geometry, along with their Marsden-Weinstein reductions. Notably, contact geometry has experienced a revival in recent years, with significant attention directed toward its application in the study of Hamiltonian systems. Additionally, its analogue for field theories, k-contact geometry, has also attracted interest. I will review modern attempts at devising a multisymplectic reduction, which has remained unsolved for approximately three decades.
