Web22 lug 2024 · We also present a simplified version of the argument that is capable of establishing Roth's theorem on arithmetic progressions of length three. In 1975, … A subset A of the natural numbers is said to have positive upper density if $${\displaystyle \limsup _{n\to \infty }{\frac { A\cap \{1,2,3,\dotsc ,n\} }{n}}>0}$$. Szemerédi's theorem asserts that a subset of the natural numbers with positive upper density contains infinitely many arithmetic … Visualizza altro In arithmetic combinatorics, Szemerédi's theorem is a result concerning arithmetic progressions in subsets of the integers. In 1936, Erdős and Turán conjectured that every set of integers A with positive natural density contains … Visualizza altro A multidimensional generalization of Szemerédi's theorem was first proven by Hillel Furstenberg and Yitzhak Katznelson using ergodic theory.

The cases k = 1 and k = 2 of Szemerédi's theorem are trivial. The case k = 3, known as Roth's theorem, was established in 1953 by Visualizza altro It is an open problem to determine the exact growth rate of rk(N).
