In the U.S., every plumbing fixture must also be coupled to the system's vent piping. [1] Without a vent, negative pressure can slow the flow of water leaving the system, resulting in clogs, or cause siphonage to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.
The Cantor set is an unusual closed set in the sense that it consists entirely of boundary points and is nowhere dense. Singleton points (and thus finite sets) are closed in T 1 spaces and Hausdorff spaces. The set of integers is an infinite and unbounded closed set in the real numbers.
An important example, especially in the theory of probability, is the Borel algebra on the set of real numbers.It is the algebra on which the Borel measure is defined. . Given a real random variable defined on a probability space, its probability distribution is by definition also a measure on the Borel a
The notion defined above is sometimes called an upward directed set. A downward directed set is defined analogously, [2] meaning that every pair of elements is bounded below. [3] [a] Some authors (and this article) assume that a directed set is directed upward, unless otherwise stated. Other authors call a set directed if and only if it is ...
Therefore, if is a union-closed family of sets, the family of complement sets to sets in relative to the universe () is closed under intersection, and an element that belongs to at least half of the sets of belongs to at most half of the complement sets. Thus, an equivalent form of the conjecture (the form in which it was originally stated) is ...
