The Piatetski-Shapiro prime number theorem

The Piatetski-Shapiro sequences are of the form Nc := ( nᶜ )ₙ₌₁^∞, where · is the integer part. Piatetski-Shapiro proved there are infinitely many primes in a Piatetski-Shapiro sequence for 1 < c < 12/11 = 1.0909 in 1953 and the best admissible range of c for this result is by Rivat and Wu for 1 < c < 243/205 = 1.1853 in 2001. In this article, we prove there are infinitely many Piatetski-Shapiro prime numbers for $1 < c < 6/5 = 1.2$ with an asymptotic formula. Moreover, we also prove an asymptotic formula for Piatetski-Shapiro primes in arithmetic progressions with $1 < c < 6/5 = 1.2$.
