Introduction to additive combinatorics lecture 11.2 --- Part of the proof of Roth's theorem
Roth's theorem, one of the fundamental results of additive combinatorics, states that for every positive δ and every positive integer k there exists a positive integer n such that every subset of {1,2,...,n} of size at least δn contains an arithmetic progression of length 3. (This was late

Introduction to additive combinatorics lecture 12.1 --- Finishing the proof of Roth's theorem
Roth's theorem on arithmetic progressions states that for every positive real number δ there exists a positive integer N such that every subset of {1,2,...,N} of size at least δN contains an arithmetic progression of size 3. In the previous video of the course I proved two important lemmas

Endre Szemerédi: In every chaos there is an order
Abstract: The chaos and order will be defined relative to three problems. 1. Arithmetic progressions This part is connected to a problem of Erdős and Turán from the 1930’s. Related to the van der Waerden theorem, they asked if the density version of that result also holds: Is it true tha

Taylor's Theorem for Remainders
Calculus: Given a Taylor polynomial for a function f(x) with n+1 derivatives, Taylor's Theorem gives us a method for estimating the error from the actual value. The example of f(x) = x^5 + 1 is given. For more videos like this one, please visit the Calculus playlists at this channel.

Theory of numbers: Fundamental theorem of arithmetic
This lecture is part of an online undergraduate course on the theory of numbers. We use Euclid's algorithm to prove the fundamental theorem of arithmetic, that every positive number is a product of primes in an essentially unique way. We then use this to prove Euler's product formula fo

Theory of numbers: Congruences: Euler's theorem
This lecture is part of an online undergraduate course on the theory of numbers. We prove Euler's theorem, a generalization of Fermat's theorem to non-prime moduli, by using Lagrange's theorem and group theory. As an application of Fermat's theorem we show there are infinitely many prim

A result that has played a central role in additive combinatorics is the statement that for every positive c there exists n such that every subset of F_3^n of density at least c contains three distinct vectors x, y and z such that x + y + z = 0. For a long time, a major open problem was to
