On b-closed spaces and θ−b-continuous functions

الملخص EN

In this paper, we give several characterizations of b-closed spaces which were introduced by J.H.

Park [Acta Math.

Hungar.

110 (4) (2006) 347-359].

We introduce and investigate a new class of functions which transform b-closed spaces to quasi H-closed spaces and introduce new regularity axioms by using b-open set san dinvestigate strongly θ-b-closedness of graphs of functions.
