What is Linear and Abstract Analysis and How Are They Applied in Science?

Click For Summary

Discussion Overview

The discussion revolves around the courses "Linear Analysis" and "Abstract Analysis," exploring their content, applications, and relevance in various fields, particularly in mathematics and physics. Participants share their experiences and seek advice on the utility of these courses in both pure and applied contexts.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • Some participants clarify that the courses in question are indeed "Linear Analysis" and "Abstract Analysis," rather than algebra.
  • One participant emphasizes the necessity of both courses for students majoring in math or physics, while suggesting that engineering students may find only Linear Algebra useful.
  • Another participant describes their experience as a physics grad student, highlighting the importance of a solid foundation in vector spaces and group theory for their thesis work on effective field theories.
  • There is a request for course descriptions, with one participant speculating that "Abstract Analysis" may be a standard second-year analysis course and "Linear Analysis" resembling functional analysis, which is perceived as more abstract and challenging.
  • Concerns are raised about the applicability of these courses in applied mathematics, with one participant expressing a desire to avoid courses that lack practical use outside of pure mathematics.
  • Another participant suggests that "Functional Analysis" (likely corresponding to "Linear Analysis") is relevant for developing theories behind solution methods for differential equations, though not strictly necessary for applying those methods.
  • One participant expresses optimism about the usefulness of the material they are learning, despite initial doubts.

Areas of Agreement / Disagreement

Participants express differing views on the relevance of the courses to applied mathematics and theoretical physics. While some assert the importance of analysis in theoretical physics, others question the practical applications of the courses in scientific contexts. No consensus is reached regarding the specific utility of the courses.

Contextual Notes

Participants note the ambiguity surrounding the term "applied mathematics," indicating that its meaning can vary significantly among individuals. This may affect the perceived relevance of the courses discussed.

Next year I have the option of studying these two courses. What are they about, and what are they used for? Has anybody taken courses in these, and if so, what did you think of them?

Do you mean "Linear and Abstract Algebra"? If so, then that would make more sense!

My answer would depend on your major. If you are majoring in math or physics, then you will need to take both of them. If you are in engineering, you will only find Linear Algebra useful.

I took both of these courses, and as a physics grad student I find them indispensable. My thesis is on effective field theories for hadrons, and one must have a solid foundation of vector spaces and group theory for that.
 
Nope, it's definitely analysis. We've got separate options for abstract algebra and linear algebra.
 
How weird... could you post the course description? Probably it is something like a real analysis course, which I would highly recommend. But from those names it's hard to tell -- are you in the States?

Thanks for the links.

"Abstract Analysis" looks to me like a fairly standard analysis course (perhaps a second year of analysis- I didn't look for prerequisites.)

"Linear Analysis" looks more like what I would call "Functional Analysis", generally speaking more "abstract" and more difficult than "Abstract Analysis"!
 
Thanks for the input. I think I'm going to take them both. Is there any use for either of them in applied mathematics? I don't really want to take something that can't be used outside pure maths. The linear analysis course seems the more interesting of the two at the moment, although that could change once I take it...
 
Certainly, I would recommend taking the "abstract analysis" course first. It will definitely help you in taking the "linear analysis" course later. (Remembering that the best thing you can do is talk to the faculty who actually teach the courses for their recomendations!)

As to how much use they are in "Applied Mathematics", that depends strongly on what you mean by "applied mathematics"- an unfortunately vague term! Some people use "applied mathematics" to mean the theory behind the kind of mathematics used in applications. Certainly, if you consider yourself a mathematician of any sort you should have as much anaysis as possible. Functional Analysis (what, I think, is your "linear analysis") is used in developing the theories behind solution methods for differential equations, among other things, but are not really necessary just for using those methods. Again, think about exactly what YOU want to do and talk to the faculty.
 
Thanks a lot for your advice. I'll go and arrange an appointment to discuss it with a member of the faculty. I meant applied to some area of science, e.g. are they of any use in theoretical physics?

Yes! If you get advanced enough, most areas of math are useful in theoretical physics. But analysis is especially useful.

Wow, that's pretty cool. At least the stuff I'm learning is only seemingly useless :wink:
