Аннотация:
In this article, we introduce the idea of
$I$-compactness as a covering property through ideals of
$\mathbb N$ and regardless of the
$I$-convergent sequences of points. The frameworks of
$s$-compactness, compactness and sequential compactness are compared to the structure of
$I$-compact space. We began our research by looking at some fundamental characteristics, such as the nature of a subspace of an
$I$-compact space, then investigated its attributes in regular and separable space. Finally, various features resembling finite intersection property have been investigated, and a connection between
$I$-compactness and sequential
$I$-compactness has been established.
Ключевые слова:
ideal, open cover, compact space,
$I$-convergence.
