Rough families, cluster points, and cores

Paolo Leonetti

We define the notion of ideal convergence for sequences $(x_{n})$ with values in topological spaces $X$ with respect to a family ${F_{η} : η \in X}$ of subsets of $X$ with $η \in F_{η}$ .…

Subcommutativity of integrals and quasi-arithmetic means

Dorota Glazowska, Paolo Leonetti, Janusz Matkowski +1

Let $(X, L, λ)$ and $(Y, M, μ)$ be finite measure spaces for which there exist $A \in L$ and $B \in M$ with either $0 < λ (A) < 1 < λ (X)$ and…

On the iterates of shifted Euler's function

Paolo Leonetti, Florian Luca

Let $φ$ be the Euler's function and fix an integer $k \geq 0$ . We show that, for every initial value $x_{1} \geq 1$ , the sequence of positive integers $(x_{n})_{n \geq 1}$ defined by $x_{n+1…
