On $ψ$ -quadratic $k$ -tuples and their generalizations

S. I. Dimitrov

In this paper, we introduce the notion of $ψ$ -quadratic $k$ -tuples. We also give examples, prove some properties and propose generalizations of these new concepts.

On $ψ$ -amicable numbers and their generalizations

S. I. Dimitrov

In this article, we study the properties of $ψ$ -amicable numbers. We prove that their asymptotic density relative to the positive integers is zero. We also propose generalizations…
