Convergence of sub-series' and sub-signed series' in terms of the asymptotic $ψ$ -density

Janne Heittokangas, Zinelaabidine Latreuch

Given a non-negative real sequence ${c_{n}}_{n}$ such that the series $\sum_{n = 1}^{\infty} c_{n}$ diverges, it is known that the size of an infinite subset $A \subset N$ can be m…

Asymptotic $ψ$ -densities of subsets of natural numbers

Janne Heittokangas, Zinelaabidine Latreuch

The sizes of subsets of the natural numbers are typically quantified in terms of asymptotic (linear) and logarithmic densities. These concepts have been generalized to weighted $w$ …
