Moore space

[′mür ‚spās]
(mathematics)
A topological space that has a sequence of coverings by open sets, such that each member of the sequence is a subcollection of the previous one, and such that, for any two points, x and y, of an open set S in the space, there is an open covering in the sequence such that the closure of any member of this covering that includes x is a subset of S and does not include y.

In general, a Moore space may not be monotonically D.
(2) The Moore space (M(X), v) is monotonically D: since the subspace X of all non-isolated points of (M(X), v) is discrete, by Theorem 1.7 of [14] (M(X), v) is monotonically D.
