چکیده
|
A topological space x is said to be τ-lindelöf space if every open cover of x contains a subcover of cardinality ≤ τ. this paper aims to study those spaces in which all points have a τ-lindelöf neighborhood, calling them locally τ-lindelöf. this work extends the known results from lindelöf and locally lindelöf spaces to τ-lindelöf and locally τ-lindelöf spaces.
