O článku:
Let $\mathcal{T}ψ$ be the $ψ$-density topology for a fixed function $ψ$. We will examine some new properties of the family of $ψ$-continuous functions (that means continuous functions $f\colon \mathbb{R} \to \mathbb{R} $ with $ψ$-density topology $\mathcal{T}ψ$ in its domain and range). In the second part of the article we will discuss functions preserving \mbox{$ψ$-density} points.
