Particular point topology — In mathematics, the particular point topology (or included point topology) is a topology where sets are considered open if they are empty or contain a particular, arbitrarily chosen, point of the topological space. Formally, let X be any set and… … Wikipedia
Excluded point topology — In mathematics, the excluded point topology is a topological structure where exclusion of a particular point defines openness. Let X be any set and pin X. A proper subset of X is open if and only if it does not contain p . There are a variety of… … Wikipedia
