Abstract:  We investigate the relationship between the space $\mathcal{Z}(R,T)$, defined as the largest closed subset of a ring $T$ with respect to a countable topology, and the classical prime spectrum ${\rm Spect}(R)$ of a subring $R$. We explore the topological properties of $\mathcal{Z}(R,T)$ and establish connections with ${\rm Spect}(R)$ under certain conditions.
Keywords:  zero-dimensional subring; filter; $\mathcal{F}$-topology; countably compact
