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 sets and investigate strongly theta-b-closedness of graphs of functions.
