Programs PDE's vs Complex analysis for physics/math major

AI Thread Summary
The discussion centers on the decision between taking Partial Differential Equations (PDEs) or Complex Analysis for an upcoming academic year. The original poster is considering the importance of PDEs for physics versus their interest in Complex Analysis and potential further study in mathematical physics. Comments highlight that while Ordinary Differential Equations (ODEs) are generally easier to solve, PDEs are crucial for applications in fields like heat transfer and nuclear engineering. Participants suggest that both subjects are valuable in physics, with some recommending that Complex Analysis be taken first due to its utility in solving certain PDEs through techniques like conformal mapping. Ultimately, the consensus leans towards taking Complex Analysis, which the original poster decides to pursue based on the feedback received.

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!
 
TL;DR Summary: I want to do a PhD in applied math but I hate group theory, is this a big problem? Hello, I am a second-year math and physics double major with a minor in data science. I just finished group theory (today actually), and it was my least favorite class in all of university so far. It doesn't interest me, and I am also very bad at it compared to other math courses I have done. The other courses I have done are calculus I-III, ODEs, Linear Algebra, and Prob/Stats. Is it a...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation. This article's date received is 2022-11-15...
