In topology and related branches of mathematics, a Hausdorff space (/ ˈhaʊsdɔːrf / HOWSS-dorf, / ˈhaʊzdɔːrf / HOWZ-dorf[1]), T2 space or separated space, is a topological space where distinct points have disjoint neighbourhoods. Of the many separation axioms that can be imposed on a topological space, the "Hausdorff condition" (T 2) is ...
Said differently, is a neighborhood of a point if and only if. Neighbourhood bases. In any topological space, the neighbourhood system for a point is also a neighbourhood basis for the point. The set of all open neighbourhoods at a point forms a neighbourhood basis at that point. For any point in a metric space, the sequence of open balls ...
The derivative of the exponential map is given by [6] (1) Explanation. X = X(t) is a C1 (continuously differentiable) path in the Lie algebra with derivative X′ (t) = dX (t) / dt. The argument t is omitted where not needed. adX is the linear transformation of the Lie algebra given by adX(Y) = [X, Y]. It is the adjoint action of a Lie ...
The right order topology on the real line is locally compact in senses (1) and (3) but not in senses (2) or (4), because the closure of any neighborhood is the entire non-compact space. The Sierpiński space is locally compact in senses (1), (2) and (3), and compact as well, but it is not Hausdorff or regular (or even preregular) so it is not ...
