Bounds on the extent of a topological space
The extent $e(X)$ of a topological space $X$ is the supremum of sizes of closed discrete subspaces of $X$. Assuming that $X$ belongs to some class of topological spaces, we bound $e(X)$ by other cardinal characteristics of $X$, for instance Lindel\"of number, spread or density.
