In mathematics, particularly in the context of set theory, an **admissible set** refers to a certain type of set that satisfies specific properties related to the theory of ordinals and higher-level set theory. In model theory and descriptive set theory, an admissible set is typically defined within the framework of **Zermelo-Fraenkel set theory (ZF)** augmented by the Axiom of Choice (though in some contexts, it is discussed without the Axiom of Choice).
The Erdős cardinal is a type of large cardinal in set theory, named after the Hungarian mathematician Paul Erdős. Large cardinals are certain kinds of infinite cardinal numbers that have strong combinatorial properties and are often used in proofs and discussions concerning the foundations of mathematics, particularly in areas that deal with set theory and the continuum hypothesis.
The term "subcompact cardinal" typically refers to a particular classification of cardinal numbers in set theory. In mathematical set theory, particularly in the context of large cardinals, the concept of "subcompact" is a specific property of certain cardinal numbers. A cardinal \( \kappa \) is said to be **subcompact** if it satisfies certain conditions related to elementary embeddings and the structure of models of set theory.

"Three men make a tiger" is a Chinese proverb that suggests that sometimes, a rumor or idea can gain strength and credibility simply through repetition, even if it is not true. The phrase conveys the notion that when enough people assert something, it can be taken as truth, regardless of its validity. The origin of the proverb lies in a story about three men discussing a tiger.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
