Is knowledge of scattering theory necessary for studying Quantum Field Theory?

AI Thread Summary
Knowledge of scattering theory is not essential for studying Quantum Field Theory (QFT), especially if one has a foundational understanding of quantum mechanics and linear algebra. Introductory QFT courses will cover necessary concepts, alleviating concerns about prior knowledge in perturbation theory. However, for advanced studies, familiarity with Lebesgue integration, distributions, functional analysis, and representations of Lie groups may be beneficial. Understanding scattering from non-relativistic quantum mechanics can also enhance comprehension, as the formalism is similar. Overall, prior exposure to these topics is helpful but not mandatory for beginning QFT.

Please let me know what lecture I have to previously take.
I already took undergraduate level lecture of quantum mechanics and mathematical physics.

And I also want to know that perturbation and scattering theory is hardly important on studying QFT..I'm so worry about that I didn't study hard when my professor dealt with that contents.



Thanks in advance and please be lenient my English cause I'm not from the English-speaking world so I do not speak English well...

For almost all introductory QFT classes it's sufficient to know the basics of quantum mechanics and linear algebra. Don't worry about not knowing any kind of perturbation theory already. Everything you need will be explained in the QFT course.

If you intend to go very deep into the subject, you will also have to learn about Lebesgue integration, distributions, functional analysis, and representations of Lie groups and Lie algebras.
 
Scattering from non-rel QM is good to know, the formalism and concepts are almost the same.
 
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.
