The Most Famous Book on Set Theory

## TL;DR

Two influential set theory books, one by Felix Hostorf and the other by Paul Hamos, are discussed, highlighting their significance and differences.

## Key Insights

• 😫 Felix Hostorf's set theory book is considered influential and was the first compilation of its kind.
• 😫 Paul Hamos' "Naive Set Theory" is a beginner-friendly version of set theory, influenced by Hostorf's work.
• 👾 Hostorf spaces, named after Felix Hostorf, are topological spaces with the property of being able to separate any two points with disjoint neighborhoods.
• 📔 The translation of mathematical books is a monumental task, as seen in the translation of Hostorf's book from German to English.
• 😥 Set theory is often the starting point in mathematics courses and is crucial for mathematicians' understanding.
• 💨 Hamos believed that solving math problems was the best way to learn mathematics effectively.
• 😫 Zorn's Lemma is an important concept in set theory frequently used in mathematical proofs.

## Transcript

hello I want to show you some of my math books so I have two books here the first one is set theory this is by Felix hostorff and so Felix hostorf was a very very famous mathematician and this book is I believe the first really popular book or maybe the first book I'm not sure but it's a very influential book on set theory I think it might be like ...

### Q: Who wrote the book "Naive Set Theory"?

The book "Naive Set Theory" was written by Paul Hamos, influenced by Felix Hostorf's set theory book.

### Q: What is the significance of Felix Hostorf in mathematics?

Felix Hostorf was a famous mathematician known for his contributions to set theory and the concept of Hostorf spaces.

### Q: What is the main difference between Felix Hostorf's set theory book and Paul Hamos' "Naive Set Theory"?

Hostorf's book is considered the first comprehensive compilation of set theory knowledge, while Hamos' book is a more beginner-friendly version with fewer topics covered.

### Q: What are Hostorf spaces?

Hostorf spaces, named after Felix Hostorf, are topological spaces in which any two points can be separated by disjoint neighborhoods.
