A note on mappings of extremally disconnected spaces
Acta Mathematica Hungarica, 1985The author studies relationships between various generalizations of continuous mappings and open mappings. In particular semi-continuous and pre-open mappings are studied. A mapping f:X\(\to Y\) is called semi- continuous if \(f^{-1}(U)\subset cl Int f^{-1}(U)\) for every open set \(U\subset Y\) whereas it is pre-open if f(V)\(\subset Int cl f(V)\) for

Extremally Disconnected Compact Hausdorff Reflection
Annals of the New York Academy of Sciences, 1992The rounding of o‐filters is introduced and this concept is used to construct an extremally disconnected compact Hausdorff reflection for a given extremally disconnected space. Some characterizations of such spaces have been obtained in terms of the rounding of o‐filters. Furthermore, relations between prime o‐filters, round o‐filters, ultra o‐filters,
