A set might be open, closed, both, or neither. In particular, open and closed sets are not mutually exclusive, meaning that it is in general possible for a subset of a topological space to simultaneously be both an open subset and a closed subset. Such subsets are known as clopen sets.

WebSets Which Are Both Open and Closed We already saw when we studied open and closed sets in the real line that it's possible for a set to be both open and closed. In general, in any metric space, the whole space X, and the empty set are always both open and closed. This means that being open or closed are not mutually exclusive alternatives. Web20 de jul. de 2012 · Closed set: Compliment of an open set, AKA R^n/O. R 2 is the compliment of the empty set so it is sufficient to prove that the empty set is open. And that follows from the logical principal that "if P then Q" is true in the case that P is false, no matter whether Q is true of false.
