Recently in Dikranjan et al. (Fund Math 249: 185–209, 2020) an uncountable Borel subgroup $$t^s_{(2^n)}({\mathbb T}) $$ (called statistically characterized subgroup) was constructed containing the Prufer group $${\mathbb Z}(2^\infty )$$ using the n

Following the line of investigation in [Linear Algebra Appl., 487, 22–42 (2015)], for y ∈ ℝ and a sequence x = (xn) ∈ l∞, we define a new notion of density δg with respect to a weight function g of indices of the elements xn close to y, wh

In this paper we extend the idea of weighted density of Balcerzak et al. (2015) by using a modulus function and introduce the idea f -density of weight g of subsets of ω ≔ { 0 , 1 , … } (at the same time extending the notion of f -density (Aizpu

In this note, continuing in the line of [2] we further consider a more general approach and for y ? R and a sequence x = (xn) ? l? we define the more general notion of IA-density of indices of those xn?S which are close to y, denoted by I?A(y) where
