    On Waring-Goldbach problem with Piatetski-Shapiro primes
    (Academic Press, 2018) Akbal, Yıldırım; Güloğlu, Ahmet M.
    In this paper, we show that all sufficiently large natural numbers satisfying certain local conditions can be written as the sum of kth powers of Piatetski-Shapiro primes, thereby establishing a variant of Waring-Goldbach problem with primes from a sparse sequence.

    Variations on a theme of Mirsky
    (World Scientific Publishing, 2022-07-05) Akbal, Yıldırım; Güloğlu, Ahmet
    Let k and r be non-zero integers with r≥2. An integer is called r-free if it is not divisible by the rth power of a prime. A result of Mirsky states that there are infinitely many primes p such that p+k is r-free. In this paper, we study an additive Goldbach-type problem and prove two uniform distribution results using these primes. We also study certain properties of primes p such that p+a1,…,p+aℓ are simultaneously r-free, where a1,…,aℓ are non-zero integers and ℓ≥1 .
