Positive proportion of short intervals containing a prescribed number of primes

Daniele Mastrostefano

We will prove that for every $m \geq 0$ there exists an $ε = ε (m) > 0$ such that if $0 < λ < ε$ and $x$ is sufficiently large in terms of $m$ and $λ$ , then $$|…

On numbers $n$ with polynomial image coprime with the $n$ th term of a linear recurrence

Daniele Mastrostefano, Carlo Sanna

Let $F$ be an integral linear recurrence, $G$ be an integer-valued polynomial splitting over the rationals, and $h$ be a positive integer. Also, let $A_{F, G, h}$ be the se…

An Upper Bound for the Moments of a G.C.D. related to Lucas Sequences

Daniele Mastrostefano

Let $(u_{n})_{n \geq 0}$ be a non-degenerate Lucas sequence, given by the relation $u_{n} = a_{1} u_{n - 1} + a_{2} u_{n - 2}$ . Let $ℓ_{u} (m) = l c m (m, z_{u} (m))$ , for $(m, a_{2}) = 1$ , where $z_{u} (m)$ is t…

Weighted Average Number of Prime $m$ -tuples lying on an Admissible $k$ -tuple of Linear Forms

Daniele Mastrostefano

We find an upper bound for the sum $\sum_{x < n \leq 2 x} 1_{P} (n + h_{i_{1}}) \dots 1_{P} (n + h_{i_{m + 1}}) w_{n}$ , where $(h_{i_{1}}, ..., h_{i_{m + 1}})$ is…

Short intervals containing a prescribed number of primes

Daniele Mastrostefano

We prove that for every nonnegative integer $m$ there exists an $ε > 0$ such that if $λ \in (0, ε]$ and $x$ is sufficiently large in terms of $m$ , then the number o…
