  • Closed and exact differential forms

    In mathematics, especially vector calculus and differential topology, a closed form is a differential form α whose exterior derivative is zero ( = 0), and an exact form is a differential form that is the exterior derivative of another differential form β. Thus, an exact form is in the image of d, and a closed form is in the kernel of d.

    For an exact form α, α = for some differential form β of one-lesser degree than α. The form β is called a "potential form" or "primitive" for α. Since d2 = 0, β is not unique, but can be modified by the addition of the differential of a two-step-lower-order form.

    Because d2 = 0, any exact form is automatically closed. The question of whether every closed form is exact depends on the topology of the domain of interest. On a contractible domain, every closed form is exact by the Poincaré lemma. More general questions of this kind on an arbitrary differentiable manifold are the subject of de Rham cohomology, that allows one to obtain purely topological information using differential methods.

    Closed set

    In geometry, topology, and related branches of mathematics, a closed set is a set whose complement is an open set. In a topological space, a closed set can be defined as a set which contains all its limit points. In a complete metric space, a closed set is a set which is closed under the limit operation.

    Equivalent definitions of a closed set

    In a topological space, a set is closed if and only if it coincides with its closure. Equivalently, a set is closed if and only if it contains all of its limit points.

    This is not to be confused with a closed manifold.

    Properties of closed sets

    A closed set contains its own boundary. In other words, if you are "outside" a closed set, you may move a small amount in any direction and still stay outside the set. Note that this is also true if the boundary is the empty set, e.g. in the metric space of rational numbers, for the set of numbers of which the square is less than 2.

  • Any intersection of closed sets is closed (including intersections of infinitely many closed sets)
  • Closed (poker)

    In the game of poker, a betting round is said to be closed if no player will have the right to raise in the round. Normally this occurs when a player calls, and the next player whose turn it is to act is the one who made the last raise, so he cannot raise further (this ends the betting round). The round can also said to be closed before it has actually ended if there are still players remaining to act, but they will not be entitled to raise either because the last raise was a sub-minimum all-in raise (see poker table stakes rules) or because the limit ("cap") on allowed raises has been reached.

    The term is also used to describe a category of poker game in which no cards held by individual players are visible to any other player before the showdown. Most forms of draw poker are closed games (draw games with a rollout are an exception). Most forms of stud poker, in contrast, are open games, because some players' cards are dealt face up or are exposed during play (blind stud games are an exception). Most community card poker games like Texas hold 'em are considered closed as well, because the only cards exposed before showdown belong to everyone; the individual players' cards are never seen until showdown.

    Wine tasting descriptors

    The use of wine tasting descriptors allows the taster to qualitatively relate the aromas and flavors that the taster experiences and can be used in assessing the overall quality of wine. Wine writers, like Karen MacNeil author of The Wine Bible, differentiate wine tasters from casual enthusiasts; tasters attempt to give an objective description of the wine's taste (often taking a systematic approach to tasting), casual enthusiasts appreciate wine but pause their examination sooner than tasters. The primary source of a person's ability to taste wine is derived from his or her olfactory senses. A taster's own personal experiences play a significant role in conceptualizing what he or she is tasting and attaching a description to that perception. The individual nature of tasting means that descriptors may be perceived differently among various tasters.

    The following is an incomplete list of wine tasting descriptors and a common meaning of the terms. These terms and usage are from Karen MacNeil's 2001 edition of The Wine Bible unless otherwise noted.
