WebMany mathematicians defined and studied soft separation axioms and soft continuity in soft spaces by using ordinary points of a topological space X. Also, some of them studied the same concepts by using soft points. In this paper, we introduce the WebMay 6, 2015 · A strongly zero-dimensional space is usually defined to be a completely regular space X such that the Stone-Cech compactification β X is zero-dimensional. Equivalently, a completely regular space X is strongly zero-dimensional if and only if whenever f: X → [ 0, 1] is continuous, then there is a clopen set C with f − 1 [ { 0 }] ⊆ C, f ...
