Discussion Overview

The discussion centers around the book "Naive Set Theory" by Paul Halmos, exploring its value for math enthusiasts. Participants share their experiences with the text, its writing style, and its role as a supplementary resource in learning set theory.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants appreciate Halmos's writing style, describing it as superb and refreshing.
  • One participant notes that the book serves as an exercise in itself, requiring readers to verify claims and fill in details.
  • There is a suggestion that the book does not develop set theory using Zermelo-Fraenkel set theory with the Axiom of Choice (ZFC), which some see as a downside.
  • Another participant mentions that while the book is useful for learning the basic language of mathematics, it may not be necessary for deeper studies in set theory.
  • Some participants recommend Jech's book for those looking to explore set theory more deeply, contrasting it with Halmos's text.
  • A participant reflects on their early experience with the book, stating it provides a foundational understanding of mathematics that may not require revisiting.
  • Another participant highlights the book's coverage of key concepts such as sets, relations, functions, and the axiom of choice, praising Halmos's communication skills.

Areas of Agreement / Disagreement

Participants express a mix of appreciation for Halmos's book as a supplementary resource and highlight its limitations for those seeking a comprehensive understanding of set theory. There is no consensus on whether it is a must-read, as opinions vary on its depth and necessity.

Contextual Notes

Some participants note that the book may not cover set theory in the context of ZFC, which could limit its applicability for more advanced studies. Additionally, the discussion reflects varying levels of experience and expectations regarding the text's content.

I skimmed this book while reading the opening chapter in the book Topology by James Munkres. The writting style of Paul Halmos is superb. There are not many problems designated as exercises; however, as I believe the author points out, the entire book is essentially an exercise. Hence, you will have plenty to do (verifying claims, filling in details, etc.)

There are really no downsides to this text. Like I mentioned earlier, I used this book as a light supplement. But, I will say that carefully working through the opening chapter in Munkres provides a very solid foundation. I really did not need this book, but it did certainly have a refreshing style!

I guess one downside is that it doesn't develop set theory using ZFC IIRC.
 
WannabeNewton, yes, you are right! I should have said that there are no downsides to the book when used as a supplement. For those interested diving deep into Set Theory (and perhaps never surfacing), Jech's tome would certainly be one route to take. =)

Warning: when he says you will never resurface, he isn't kidding.
 
Naive set theory is a book I read as a very young student, maybe in high school. You read it once, it gives you the universal language of mathematics and you never need to consult it again. I recommend it to anyone to learn the basic language of the subject. Nothing deep here, but everything is useful.
 
This remains one of my favourite math texts. It gives you the language of sets and relations, functions and cartesian products, equivalence classes and 'the axiom of choice', plus a little more advanced set theory, in an easily digested format. You'll also understand Russell's paradox in a new way.

Besides Halmos is a sublime communicator - one of the best in the business. You can pick up reprints up for $10-$15, and they're worth it purely for the example of crystal clear mathematical communication.
