The Piatetski-Shapiro prime number theorem

TL;DR

This paper proves the existence of infinitely many primes within Piatetski-Shapiro sequences for certain exponents between 1 and approximately 1.1612, using a novel bound for type I sums.

Contribution

It establishes the infinitude of primes in Piatetski-Shapiro sequences for a wider range of c values than previously known, with an asymptotic formula and a new bound for type I sums.

Findings

Infinitely many primes in Piatetski-Shapiro sequences for 1 < c < 1.1612

Derived a new bound for related type I sums

Provided an asymptotic formula for prime counts in these sequences

Abstract

The Piatetski-Shapiro sequences are of the form $\mathcal{N}_{c} := (\lfloor n^{c} \rfloor)_{n=1}^\infty$, where $\lfloor \cdot \rfloor$ is the integer part. It is expected that there are infinitely many primes in a Piatetski-Shapiro sequence for $c \in (1,2)$. In this article, we prove there are infinitely many Piatetski-Shapiro prime numbers for $1 < c < 1.1612\dots$ with an asymptotic formula. As a key idea, we prove a new bound for related type $I$ sum.
