Discussion Overview

The discussion centers around which chapters of the Munkres Topology textbook are essential for physicists, particularly in the context of learning differential geometry. Participants express varying opinions on the necessity of Munkres for those with a physics background and the relevance of specific chapters.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that a physicist's understanding of topology may not require Munkres, proposing that "Topology for physicists" could suffice.
  • Another participant expresses a desire to learn differential geometry from a mathematical perspective, indicating a need to understand concepts like Hausdorff spaces and paracompactness more thoroughly.
  • A different participant recommends chapters 2-4 and possibly chapter 6 of Munkres for someone interested in these topics, while noting that chapter 1 may be useful for understanding conventions used later in the book.
  • There is a mention that chapter 9 contains essential material for those not focused on algebraic topology.
  • One participant argues that while learning mathematics in a non-physicist way may be beneficial, it is not essential for physics.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of Munkres for physicists, with some arguing it is not essential while others suggest certain chapters may be beneficial. No consensus is reached regarding which chapters are universally essential.

Contextual Notes

Some participants highlight that their recommendations depend on individual goals and backgrounds, indicating that the relevance of specific chapters may vary based on prior knowledge and intended applications.

I would like to know which chapters in Munkres Topology textbook are essential for a physicist. My background in topology is limited to the topology in baby Rudin, Kreyzig's functional, and handwavy topology in intro GR books. I feel like the entire book isn't necessary, but I could be mistaken.

A physicist, even a mathematical physicist, can live without ever reading Munkres or anything equivalent. Books entitled "Topology for physicists" or something alike should be sufficient, and such books do not pay much attention to things studied in Munkres-like books. But of course, if you want to know more topology than a physicist really needs to know, you are welcome to read Munkres or anything else which you find interesting.

I would like to learn differential geometry the mathematicians way, not the physicists way. I usually just gloss over passages about Hausdorff spaces, second countable, paracompact and things of that nature and I would like to stop doing that.
 
Note that I don't have a physics background, but I'm buried in Munkres right now.

Based on what you've said here I'd think you'd want 2-4 of Munkres and then maybe 6 (since you mentioned paracompact). 6 is not dependent on 5, but 5 is short.

Chapter 1 is a review of set theory and logic and might still be helpful if not for the review itself then to know what conventions he uses later.

It doesn't sound like you need algebraic topology, but the essentials are in chapter 9.

Check his preface for some of his own recommendations.

That's fine, but I don't think that learning math the non-physicist way can be essential for physics. Maybe useful, complementary, or deepening, but not essential.
