topology and related fields of mathematics, a topological space X is called a regular space if every closed subset C of X and a point p not contained...

Tychonoff spaces and completely regular spaces are kinds of topological spaces. These conditions are examples of separation axioms. A Tychonoff space is any...

Hausdorff. Every regular second-countable space is completely normal, and every regular Lindelöf space is normal. Also, all fully normal spaces are normal (even...

Regular space (or T 3 {\displaystyle T_{3}} ) space, a topological space in which a point and a closed set can be separated by neighborhoods Regular army...

metrization theorem. This states that every Hausdorff second-countable regular space is metrizable. So, for example, every second-countable manifold is metrizable...

call locally compact. Spaces satisfying condition (4) are exactly the locally compact regular spaces. Indeed, such a space is regular, as every point has...

class of regular languages. In practice, most nonregular problems are solved by machines taking at least logarithmic space. To locate the regular languages...

non-breaking space ( ), also called NBSP, required space, hard space, or fixed space (in most typefaces, it is not of fixed width), is a space character...
