    Course description

    Groups and their representations form the mathematical description of symmetries. This course introduces you to representation theory, with particular emphasis on Lie groups and their Lie algebras which account for continuous symmetries. Mathematical applications of the theory range from combinatorics to geometry and topology. Lie groups of importance to physics include the group of coordinate transformations of spacetime in special relativity, and the group of gauge transformations in theories of particle physics.

    Contents

    Grading
    The course grade is determined by a score consisting of
    • up to 24 points from the exam (4 problems worth 6 points each)
    • up to 6 bonus points from solutions to problems

    Exam
    The exam will be held on:
    • April 17 at 13:00-16:00.
    The retake exam is on:
