有限指数子格

Sublattices of finite index

Chunlei Liu

摘要:

在有限参数$s$的Gowers逆猜想和Möbius猜想的假设下,Green-Tao证明了Dickson猜想对于复杂度至多为$s$的线性映射的格的猜想.本文将Green-Tao定理推广到Dickson猜想上,证明了:若$L$是复杂度为$s$的线性映射的值域,而$L_1$是$L$的有限指数子格,则$L_1$是复杂度为$s$的线性映射的值域.

英文摘要:

Assuming the Gowers Inverse conjecture and the Möbius conjecture for the finite parameter $s$, Green-Tao verified Dickson's conjecture for lattices which are ranges of linear maps of complexity at most $s$. In this paper, we reformulate Green-Tao's theorem on Dickson's conjecture, and prove that, if $L$ is the range of a linear map of complexity $s$, and $L_1$ is a sublattice of $L$ of finite index, then $L_1$ is the range of a linear map of complexity $s$.
