Summer Semester of 2022: General Relativity.

  • Lectures (IRIS 1.207): Wednesdays 15:15-16:45, Fridays 15:15-16:45 (biweekly)

  • Tutorials (IRIS 1.207): Fridays 15:15-16:45 (biweekly, possibly to be shifted due to Dies academicus)

  • We will have a 5 minute break in the middle of our time-slots, and run over at the end by 5 minutes.

  • NO LECTURE OR TUTORIAL on Wednesday 27 April (Dies academicus from noon).

Course organization:

  • We will mainly follow the book "Spacetime and Geometry" by Sean M. Carroll. As an alternative, if necessary you can make do with the "Lecture Notes on General Relativity" by the same author, which covers roughly the same material.

  • There will be a written examination at the end of the course on 27 July 2022, 15:00-17:00.

The second, main part of the class, on Lie groups, will follow sections of the book ''Lie Groups, Lie Algebras, and Representations'' by Brian C. Hall, second edition. Sections discussed are listed below, with corresponding sections for the first edition of the book by Hall in [square brackets].

  • Exercise sheets should be completed by the start of the tutorial class, where students will present their solutions.

  • There will be a written examination at the end of the course, on Tuesday the 23rd of July, 11:00-13:00 (it starts at 11 sharp!). Question hours: 12 July 11:00-12:00, 22 July 14:00-15:00.

  • Lecture 11 - 2.4, 2.5 [2.4, 1.7 except this misses P = exp X]

  • Lecture 13 - remainder of 3.4, 3.5, 3.6 [remainders of 2.5, 2.6, and 2.8]

  • Lecture 14 - 3.7, most of 3.8 [first half of 2.7]

  • Lecture 15 - Remainder of 3.8, 4.1, most of 4.2 [remainder of 2.7, 4.1, 4.2, 4.3.1-3, most of 4.3.4]

  • Lecture 20 - 5.7, 5.8 [3,6, 3.7]

  • Lecture 21 - 5.9, 5.10 [3.8, slightly different discussion but basically the same material covered]

We did not get to the final topic of the Lorentz group and algebra (relation to SL(2,C), topology, finite dimensional representations). Most of what I would have liked to discuss can be found in "The Quantum Theory of Fields" by Steven Weinberg, volume 1, section 2.3, and pages 86-89, 214, 216-217, 229-232, though of course this does not emphasize connections to the earlier lectures.
