Fuzzy pairwise extremally disconnected spaces

Fuzzy Sets and Systems, 1998
The concept of fuzzy extremally disconnected spaces, due to \textit{B. Ghosh} [ibid. 46, No. 2, 245-250 (1992; Zbl 0765.54004)] is generalized. A fuzzy bitopological space \((X,\tau_1,\tau_2)\) is said to be: (a) \((\tau_i, \tau_j)\)-fuzzy extremally disconnected \(((\tau_i, \tau_j)\)-FED) if the \(\tau_j\)-closure of every \(\tau_i\)-fo (fuzzy-open ...

Extremally Disconnected Spaces and Absolutes

1988
One of the best behaved classes of functions encountered in general topology is the class of perfect functions, which was discussed in 1.8. As we have already seen, two topological spaces, one of which is the perfect continuous image of the other, will have many topological properties in common. (Examples of a number of such properties are given in 1J.)

Extremally Disconnected Compact Hausdorff Reflection

Annals of the New York Academy of Sciences, 1992
The 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,

Properties of L-Extremally Disconnected Spaces

2010
The concept of L-extremally disconnected spaces is introduced and investigated in this paper, which is the generalization of the concept of fuzzy extremally disconnected spaces due to Ghosh. In L-extremally disconnected spaces, it is proved that the concepts of semi-open, pre-open and alpha-open sets are uniform. We will also show that two theorems are

The k-Extremally Disconnected Spaces as Projectives

Canadian Journal of Mathematics, 1964
The letter k denotes an infinite cardinal. A space is a compact Hausdorff space unless otherwise indicated. A space is called extremally disconnected (k-extremally disconnected) if it is the Stone space for a complete (k-complete) Boolean algebra. A map is a continuous function from one space into another.
