| The flag algebra method, invented by Razborov, is a very general machinery and has been widely used in extremal graph theory. In this talk, I will give an introduction to the flag algebra method, explaining basic terms and showing how it works by giving a complete proof of Mantel's theorem using the flag algebra method. I will also show results we proved using this method, including upper bounds on the number of edges of $C_4$-free or $C_6$-free subgraphs of hypercubes, minimum number of monotone subsequences of length 4 in permutations of [n]. |
