On weak forms of preopen and preclosed functions. (English). Archivum Mathematicum, vol. 40 (2004), issue 2, pp. 119-128
MSC: 54A40, 54C08, 54C10, 54D10 | MR 2068686 | Zbl 1111.54011
Keywords:
preopen sets preclosed sets; weakly preclosed functions; extremally disconnected spaces; quasi H-closed spaces
Summary:
In this paper we introduce two classes of functions called weakly preopen and weakly preclosed functions as generalization of weak openness and weak closedness due to [26] and [27] respectively. We obtain their characterizations, their basic properties and their relationshisps with other types of functions between topological spaces.
