Restriction estimates with sifted integers

TL;DR

This paper extends restriction estimates to integers sifted by prime-related subsets, generalizing previous results by Green-Tao.

Contribution

It introduces new restriction estimates for integers sifted by prime-dependent subsets, broadening the scope of prior Green-Tao results.

Findings

Established restriction estimates for sifted integers.

Generalized Green-Tao restriction estimates to broader settings.

Enhanced understanding of prime-based sieve methods.

Abstract

Let $\mathcal{P}$ be a subset of primes and for each prime $p\in \mathcal{P}$, consider a subset $\mathcal{L}_p$ of $\mathbb{Z}/p\mathbb{Z}$. We provide restriction estimates with integers $\leq N$ sifted by $(\mathcal{L}_p)_{\substack{p\leq z\\ p\in \mathcal{P}}}$. This generalizes a result of Green-Tao [3] on the restriction estimates.
