On the $P_{1}$ property of sequences of positive integers

Tigran Hakobyan

It is well-known that for any non-constant polynomial $P$ with integer coefficients the sequence $(P (n))_{n \in N}$ has the property that there are infinitely many prime nu…

On the unboundedness of common divisors of distinct terms of the sequence $a_{n} = 2^{2^{n}} + d$ for $d > 1$

Tigran Hakobyan

It is well-known that for any distinct positive integers $k$ and $n$ , the numbers $2^{2^{k}} + 1$ and $2^{2^{n}} + 1$ are relatively prime. In this paper we consider the situation when 1 i…
