On a variation of selective separability: S-separability

Debraj Chandra, Nur Alam, Dipika Roy

A space $X$ is M-separable (selectively separable) (Scheepers, 1999; Bella et al., 2009) if for every sequence $(Y_{n})$ of dense subspaces of $X$ there exists a sequence $(F_{n})$ suc…

On a variation of selective separability using ideals

Debraj Chandra, Nur Alam, Dipika Roy

A space $X$ is H-separable (Bella et al., 2009) if for every sequence $(Y_{n})$ of dense subspaces of $X$ there exists a sequence $(F_{n})$ such that for each $n$ $F_{n}$ is a finite sub…

Certain results on selection principles associated with bornological structure in topological spaces

Debraj Chandra, Subhankar Das, Nur Alam

We study selection principles related to bornological covers in a topological space $X$ following the work of Aurichi et al., 2019, where selection principles have been investigate…
