Theorems List

This page contains list of mathematical Theorems which are at the same time (a) great, (b) easy to understand, and (c) published in the 21st century. See here for more details about these criteria. Click on any theorem to see the exact formulation, or click here for the formulations of all theorems. You can also view theorems by broad subject category: combinatorics, number theory, analysis, algebra, geometry and topology, logic and foundations, probability and statistics, mathematics of computation, and applications of mathematics.

On this page, the theorems are sorted by submission date (to arxiv or journal, whichever is first). See here for the list of recently added theorems. Also, you can download the excel document with the full list of Theorems, where you can search, sort, and filter them by date, paper title, author, journal, or subject category.
