Is differential equation required to study real analysis?

Click For Summary

Discussion Overview

The discussion revolves around whether differential equations are a prerequisite for studying real analysis, particularly in the context of "baby Rudin," and their relevance to measure theory and stochastic calculus.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants argue that differential equations are not a prerequisite for real analysis or measure theory.
  • Others suggest that knowledge of differential equations is necessary for stochastic calculus.
  • One participant questions whether ordinary differential equations (ODE) are sufficient for stochastic calculus or if partial differential equations (PDE) are also required.
  • A participant mentions that having a background in analysis may be beneficial before studying differential equations.
  • There is a request for recommendations on resources for learning PDEs, indicating a perceived gap in available materials.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of differential equations for real analysis and stochastic calculus, indicating that multiple competing perspectives remain unresolved.

Contextual Notes

Some claims depend on the definitions of differential equations and their applications in various mathematical contexts, which may not be universally agreed upon.

Hi all,
Is differential equation a prerequisite to study real analysis (in context of baby Rudin)? And does it have any use in measure theory or Stochastic Calculus?
Thanks in advance.

No, I would not consider differential equations as a prerequisite for either of those courses.

What about Stochastic Differential Equations?
 
No. In fact, it would almost certainly be better to know some analysis before studying DE's.
 
When we say DE does it also include PDE or does ODE is enough for stochastic calculus? Also does anyone know the best source for PDEs as at Paul's notes it's very limited & doesn't have examples & exercises?
