More on Cardinality Bounds Involving the Weak Lindelöf degree
Angelo Bella, Nathan Carlson, Ivan Gotchev
We give several new bounds for the cardinality of a Hausdorff topological space involving the weak Lindelöf degree . In particular, we show that if is extremally dis…

On cardinality bounds involving the weak Lindelöf degree
Angelo Bella, Nathan Carlson
We give a general closing-off argument in Theorem 2.1 from which several corollaries follow, including (1) if is a locally compact Hausdorff space then ,…
