Difficulty of Topology vs Differential Geometry

Click For Summary

Discussion Overview

The discussion revolves around the decision-making process of a student contemplating whether to take a course in topology or differential geometry, alongside real analysis and advanced linear algebra. Participants explore the perceived difficulty of each subject and their relevance to one another.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Meta-discussion

Main Points Raised

  • One participant expresses uncertainty about the difficulty of topology versus differential geometry, noting the different formats of assessment in each course.
  • Another participant suggests that topology is fundamental in mathematics and may be easier, while also indicating that it would benefit the student's understanding of differential geometry in the future.
  • Some participants argue that topology is more important than differential geometry and that it complements real analysis well, potentially making differential geometry easier later on.
  • A suggestion is made for the student to share the syllabi of both courses for better advice.
  • Two participants strongly advise against taking either course if the student is already feeling overloaded with their current math classes.
  • One participant questions whether topology is a prerequisite for differential geometry, highlighting the importance of understanding point-set topology for discussing differentiable manifolds.
  • Concerns are raised about the potential challenges of taking differential geometry without prior experience in real analysis.

Areas of Agreement / Disagreement

Participants generally agree that both subjects are important and that topology may provide foundational knowledge beneficial for differential geometry. However, there is no consensus on which course is definitively more difficult, and opinions vary on the implications of the student's current workload.

Contextual Notes

Some participants note the importance of course syllabi for a more informed decision. There is also mention of the potential challenges posed by the student's current course load and the prerequisites for differential geometry.

So I need to decide by tomorrow, whether I'll be taking topology or diff geo, (along with real analysis and advanced linear algebra). I've sat in on both classes for the first lecture, and I'm still not certain which class would be more difficult. My diff geo class has no exams, and instead requires a presentation and an expository paper at the end of the semester. Anyone know what that might entail? Topology is, however, the typical problems sets and exam format.

I feel like I'm already overloading on my math classes, so I would like your opinion on which class to take.

Tough call. Is it an introductory topology course (i.e. point-set topology)? Keep in mind that topology is an absolutely fundamental subject in mathematics; it would be very good for you to have some experience with it. As far as difficulty goes, I suspect that you might have an easier time with the topology course (not to mention that having a topology course under your belt would make diff. geometry easier in the future).
 
Indeed, topology is much more important than differential geometry (that doesn't mean that differential geometry isn't important, but just that topology occurs more often).
Furthermore, topology goes very well with your real analysis class, so the two classes will complement each other.

It's also better (and more natural) to do differential geometry from a topology point-of-view. So if you're set on doing differential geometry, then you need topology sooner or later anyway.

As for difficulty, I would say that both subjects are as difficult.
 
Inkit, I think if you post the syllabi and what each class intends to cover, people will have a better time advising you. Both are introductory classes.
 
if you are ALREADY FEELING OVERLOADED, DO NOT TAKE EITHER ONE.

Agree 100%.
 
I don't know anything about differential geometry, but I think topology is probably a prerequisite?

I mean how do you even talk about a differentiable manifold without knowing the basic terminology of a point-set topology course?

Wait I read your OP again and yeah if you're taking your first actual real analysis class then taking differential geometry might be a problem... because differential geometry is doing analysis on spaces more general than Euclidean space?
