PDE's vs Complex analysis for physics/math major

Click For Summary

Discussion Overview

The discussion revolves around the decision-making process for course selection between Partial Differential Equations (PDEs) and Complex Analysis for a physics/math major. Participants explore the relevance and applications of each subject within the context of physics and mathematical physics.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant expresses a preference for PDEs due to their importance in physics but also has an interest in Complex Analysis for its pure mathematical appeal.
  • Another participant notes that while ODEs are simpler, PDEs were useful in their experience with heat transfer and nuclear engineering.
  • Some participants suggest that both classes are of comparable utility in physics and recommend choosing based on personal interest.
  • One participant advises taking Complex Analysis before PDEs, highlighting its usefulness in solving certain PDEs through techniques like conformal mapping.
  • Another participant echoes the recommendation for Complex Analysis first, mentioning the potential for learning Fourier analysis in the PDE class.
  • A later reply indicates a decision to lean towards Complex Analysis based on the feedback received.

Areas of Agreement / Disagreement

Participants generally agree that both courses are valuable, but there is no consensus on which should be taken first. Multiple competing views exist regarding the order and importance of each subject.

Contextual Notes

Some participants express uncertainty about the specific applications of Complex Analysis in physics, and there are varying opinions on the relative difficulty of PDEs compared to ODEs.

Who May Find This Useful

Hi guys. It's almost time to choose my courses for this year. I'm torn between taking PDE's due to how important it is for physics, or complex analysis due to just liking pure maths. If I do well enough, I'm *possibly* looking to do further study in mathematical physics. I was thinking that if the PDE class is anything like the ODE class, I might be able to get away with just learning the material myself as I need it, when the time comes.

Comments appreciated. Also, does complex analysis have much application in physics?

ODEs are far simpler in my opinion to solve. While I enjoyed my PDE class what's called advanced engineering mathematics at my school, it was a pain compared to ODEs which are pretty easy to solve, especially after dealing with them in my engineering courses so much. PDE were useful when I took heat transfer, and fundamentals of nuclear engineering. Infinite series too

Generically speaking the classes are of comparable utility in physics. Choose whichever interests you more.

Eventually, you are going to need to take a course in both PDEs and complex analysis. In fact, I recommend that you take the complex analysis course first. Complex variables can be useful in solving certain PDEs, especially in the use of conformal mapping techniques for solving 2-D PDEs.

I would almost advise complex analysis before PDE's, though you should take both, because of the Fourier analysis that you may learn in PDE class.

Thanks for the replies everyone. I was leaning toward complex analysis and judging from the replies here, it wouldn't be a bad choice. So complex analysis it is!
