摘要：Furstenberg-Sarkozy theorem states that if p(n) is a polynomial with integer coefficients such that p(0) = 0, then for any set E of positive upper density in N = {1,2,...} there are many solutions to the equation x-y = p(n) where x and y are in E and n is in N. We will discuss various proofs of this theorem and its generalizations such as the Bergelson-Leibman's polynomial Szemeredi theorem.
