Notes on the Combinatorial Fundamentals of Algebra
by Darij Grinberg
Publisher: arXiv.org 2021
Number of pages: 1359
Description:
This is a detailed survey, with rigorous and self-contained proofs, of some of the basics of elementary combinatorics and algebra, including the properties of finite sums, binomial coefficients, permutations and determinants. It is entirely expository and written to a large extent as a repository for folklore proofs; no new results appear.
