On the cardinality of the θ-closed hull of sets II / Cammaroto, F.; Catalioto, A.; Pansera, B. A.; Porter, J.. - In: FILOMAT. - ISSN 0354-5180. - 27:6(2013), pp. 1107-1111. [10.2298/FIL1306107C]
abstract:
The research in this paper is a continuation of the investigation of the cardinality of the θ-closed hull of subsets of spaces. This research obtains new upper bounds of the cardinality of the θ-closed hull of subsets using cardinal functions of θ-bitightness ([8]), finite θ-bitightness ([7]) and θ-bitightness small number ([7]) of spaces. In the final section, examples of spaces are presented including one that answers a question posed in [4] and [6].
