Maths courses for theoretical physics

Click For Summary

Discussion Overview

The discussion revolves around the selection of mathematics courses for students pursuing theoretical physics, particularly in the context of a UK university curriculum. Participants explore various mathematical topics relevant to theoretical physics, including differential geometry, topology, solitons, elliptic functions, and abstract algebra, while considering their implications for future studies in areas like general relativity and quantum field theory.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant expresses interest in differential geometry and topology, citing their relevance to general relativity and string theory, while also considering solitons and elliptic functions.
  • Another participant suggests opting for advanced abstract algebra courses, such as group theory or Lie groups, emphasizing their importance in theoretical physics, particularly in particle physics.
  • Some participants agree with the suggestion to focus on advanced algebra, while others note that these options are not available to the original poster.
  • A participant points out the necessity of courses in statistical thermodynamics and electromagnetism, questioning the completeness of the curriculum listed by the original poster.
  • There is a discussion about the importance of analysis, particularly a course on calculus on manifolds, in relation to understanding differential geometry.
  • Another participant proposes algebraic topology as a potential course of interest.
  • One participant advises consulting the department about the possibility of taking courses not included in the program, suggesting that abstract algebra is essential for mathematics students.
  • A later reply raises the consideration of achieving high marks in chosen modules as a priority for future studies.

Areas of Agreement / Disagreement

Participants express a range of opinions on the best courses to take, with some advocating for advanced algebra while others focus on geometry and topology. There is no consensus on a definitive course selection, and multiple competing views remain regarding the importance of various mathematical topics.

Contextual Notes

Participants note limitations in course availability and prerequisites, which affect the choices for the original poster. The discussion reflects a variety of perspectives on the relevance of different mathematical areas to theoretical physics without resolving the uncertainties involved.

I'm choosing 3 maths modules for next year (my third in Maths and Physics, in a UK university) with a view to studying theoretical physics thereafter (starting off with general relativity, quantum field theory and most likely strings, and working outwards from there depending on where I am- possibly to particle theory, black holes, cosmology etc.) The options I'm seriously looking at are courses in differential geometry; topology; solitons; and elliptic functions. I think the first two are all but definite choices (they look interesting, and I understand differential geometry is at the heart of GR, while topology is useful in string theory?), so it's really one from solitons or elliptic functions. My course booklet suggests that elliptic functions have some use in theoretical physics, although precisely what it is eludes me. The relevance of solitions seems more apparent, although the actual maths of elliptic functions seems more interesting (so far as I can tell without actually studying both courses!)
Any thoughts? I'd be particularly appreciative if someone could explain the relevance of elliptic functions to physics. Many thanks.
 
Physics news on Phys.org
Personally, I'd choose neither and instead opt for a course in some sort of advanced abstract algebra, like advanced group theory or lie groups, unless you're already well-versed in these. Knowing how to play with groups is a very important part of theoretical physics, especially particle physics.
 
I second that
 
(1) Lie Algebras, Group Representation Theory, Operator Algebras
(2) Differential Geometry and Topology
 
Thanks for the responses- Lie Algebras etc aren't options availble to me I'm afraid! These are courses intended for single honours maths undergrads without regard to theoretical physics; the necessary group theory is covered within the specialist particle theory MSc /PhD lecture course. Such pure maths courses as focus on algebra I don't have the necessary prerequisites for from 2nd year.
If anyone is curious as to the complete options list:

Your curriculum listed on that website looks awfully incomplete. You'll want to take the courses in stat. thermo and EM for one (this is the first time I've seen a physics program without compulsory EM, not to mention listing EM as a math course); Analysis is also a must. Once you're done with those basics, then you can move on to the nice stuff such as diff geometry, topology, PDE, GR and other such courses.
 
Stat thermo and EM have been covered in 2nd year physics modules; there's also further courses within the 3rd year physics modules. When you say "analysis", I'm guessing you mean to the level of the "analysis III" module about calculus on manifolds?
 
What about Algebraic Topology ?
 
Yes I meant Analysis III (Although I don't get why it's called analysis 3 if it's your first course in analysis, but whatever). Basically, it introduces one-forms, and you absolutely need that everywhere. Not to mention that understanding these manifolds will make things like differential geometry much easier to digest.

after looking at your list i'd go w/ Diff Geo, topology, and either E&M, PDE or Dynamical Sys
then in year 4 take Alge. topology;
however
I would consult your dep. and see if you can take a pure algebra course ie. Abstract Algebra or some form of Group theory.
Yes I see that those courses aren't part of your modules for joint honours math+ physics however does your school offer a pure mathe degree, I imagine your math dept. must offer an abstract algebra course

Well just a tip.
I too learn maths and physics (but in israel), and i for example asked for permission to learn logic which wasn't part of my modules' options, I think that you can do so as well, i.e request to learn a course not included in your programme.
Although I think that taking an abstract algebra,differential geometry and topology courses are a must for every maths student, due to time constraints and the work load, not everyone can handle this, that's why it's not mandatory.

Are you thinking of doing an MSc after a BSc or straight to research? Honestly, it'd probably be better to choose modules where you can get the highest marks in.
