Discussion Overview

The discussion centers around the prerequisites for an introductory course on partial differential equations (PDEs), Fourier series, and boundary value problems. Participants explore the necessity of vector calculus and other mathematical concepts in preparation for the course.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant inquires about the necessity of vector calculus, specifically asking if knowledge of Green's Theorem and Stokes' Theorem is required.
  • Another participant asserts that vector calculus is not typically needed for an introductory PDE course, suggesting that familiarity with multivariable calculus and ordinary differential equations (ODEs) is sufficient.
  • A different viewpoint indicates that while vector calculus may not be crucial, an upper-level PDE course could involve significant analysis.
  • One participant shares their experience from a graduate-level PDE course, noting the use of gradients, cross products, and the divergence theorem, while cautioning that these topics may not be relevant in an introductory course.
  • A question is raised regarding the necessity of complex analysis for an upper-level applied PDE course.
  • Another participant expresses relief, feeling reassured that they have sufficient analysis knowledge for the course.
  • One participant mentions that the most advanced mathematical concept needed may be the Residue theorem from complex analysis, with other material being derived from basic calculus and analysis.

Areas of Agreement / Disagreement

Participants express differing opinions on the importance of vector calculus and analysis for the introductory PDE course. Some believe it is not necessary, while others suggest that certain concepts may be beneficial or required, indicating that the discussion remains unresolved.

Contextual Notes

Participants reference varying levels of courses (introductory vs. upper-level/graduate) and their respective content, which may influence the relevance of vector calculus and analysis. There is also mention of specific mathematical theorems that may or may not be covered.

Hi everybody.
I need to take a course this spring called "intro to partial differential equations, Fourier series, and boundary value problems", and I'm wondering, how much vector calculus (if any) should I learn before this course starts? I have multivariable calculus and ODEs down just fine, but I don't have vector calculus. For example, would I have to know Green's Theorem and Stokes' Theorem?

I didn't use any vector calculus in my pde course. I doubt you will either. If you know multivariable calculus and ode's, you should be fine.
 
Vector calculus will not be the most crucial.

But an upper level PDEs course can be heavy on analysis.
 
It depends really, because in my PDE course we used gradients and cross products in the throughout the course (Existence and uniqueness), and started using the divergence theorem and Green's identities when we were looking at the Laplace equation. We also did basic analysis.

However, my PDE course was a upper level/graduate course, so you may not encounter the things I am talking about in an intro course, but I would suggest at least looking at gradients, dot products, and cross products if you can.

Good luck.
 
Would you need complex analysis for such a class (upper-level "applied" PDE)?
 
Alright thanks guys! Looks like I was worrying over nothing. If it turns out that I need analysis then I've learned enough analysis for it already.
 
I had a similarly-titled course. The most sophisticated math you need to know is probably the Residues theorem from complex analysis, everything else just comes straight from calculus/analysis and very basic ODE's.
