报告摘要:Let "large'' be any of piecewise syndetic, central, central*, thick, PS*, IP*, IP$_{<\omega}$*', IP$_n$*, or $\Delta$*. It was asked by Bergelson and Hindman whenever $A$ is large, whether the set $\{(m,n)\in \N^2:m+p_1(n),m+p_2(n),\dots,m+p_d(n)\in A\}$ be large in the same sense. Huang, Shao and Ye confirmed the question for subsets with piecewise syndeticity. In this talk, we present recent progress on the rest of Bergelson-Hindman's question.
