Let $k \in \mathbb{Z}_+$ and $(X,\mathcal{B}(X),\mu)$ be a probability space equipped with a family of commuting invertible measure-preserving transformations $T_1,\ldots,T_k: X\to X$. Let $P_1,\ldots,P_k\in \mathbb{Z}[n]$ be polynomials with integer coefficients and distinct degrees. We establish pointwise almost everywhere convergence of … Continue reading The multilinear circle method and a question of Bergelson
