Mathematics

*Continuity (mathematics)
In mathematics, the terms continuity, continuous, and continuum are used in a variety of related ways.

In probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. It is a mathematical description of a random phenomenon i ...

or random variable in probability and statistics
** Continuous game
A continuous game is a mathematical concept, used in game theory, that generalizes the idea of an ordinary game like tic-tac-toe (noughts and crosses) or checkers (draughts). In other words, it extends the notion of a discrete game, where the playe ...

, a generalization of games used in game theory
** Law of Continuity
The law of continuity is a heuristic principle introduced by Gottfried Leibniz based on earlier work by Nicholas of Cusa and Johannes Kepler. It is the principle that "whatever succeeds for the finite, also succeeds for the infinite". Kepler used ...

, a heuristic principle of Gottfried Leibniz
* Continuous function
In mathematics, a continuous function is a function such that a continuous variation (that is a change without jump) of the argument induces a continuous variation of the value of the function. This means that there are no abrupt changes in val ...

** Scott continuity In mathematics, given two partially ordered sets ''P'' and ''Q'', a function ''f'': ''P'' → ''Q'' between them is Scott-continuous (named after the mathematician Dana Scott) if it preserves all directed suprema. That is, for every directed sub ...

, for functions between posets
** Continuity (set theory), for functions between ordinals
** Continuity (category theory), for functors
** Graph continuity, for payoff functions in game theory
* Continuity theorem may refer to one of two results:
** Lévy's continuity theorem, on random variables
** Kolmogorov continuity theorem, on stochastic processes
* In geometry:
** Parametric continuity
In mathematical analysis, the smoothness of a function is a property measured by the number of continuous derivatives it has over some domain, called ''differentiability class''. At the very minimum, a function could be considered smooth if ...

, for parametrised curves
** Geometric continuity, a concept primarily applied to the conic sections and related shapes
* In probability theory
** Continuous stochastic process
Science

*Continuity equation
A continuity equation or transport equation is an equation that describes the transport of some quantity. It is particularly simple and powerful when applied to a conserved quantity, but it can be generalized to apply to any extensive quantity. S ...

s applicable to conservation of mass, energy, momentum, electric charge and other conserved quantities
* Continuity test
In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit).
A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing com ...

for an unbroken electrical path in an electronic circuit or connector
* In materials science:
** a colloidal system, consists of a dispersed phase evenly intermixed with a continuous phase
** a continuous wave
A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency, typically a sine wave, that for mathematical analysis is considered to be of infinite duration. It may refer to e.g. a laser or particle ...

, an electromagnetic wave of constant amplitude and frequency
Entertainment

*Continuity (broadcasting)
In broadcasting, continuity or presentation (or station break in the U.S. and Canada) is announcements, messages and graphics played by the broadcaster between specific programmes. It typically includes programme schedules, announcement of th ...

, messages played by broadcasters between programs
* Continuity editing
Continuity editing is the process, in film and video creation, of combining more-or-less related shots, or different components cut from a single shot, into a sequence to direct the viewer's attention to a pre-existing consistency of story across b ...

, a form of film editing that combines closely related shots into a sequence highlighting plot points or consistencies
* Continuity (fiction)
In fiction, continuity is a consistency of the characteristics of people, plot, objects, and places seen by the reader or viewer over some period of time. It is relevant to several media.
Continuity is particularly a concern in the production of ...

, consistency of plot elements, such as characterization, location, and costuming, within a work of fiction (this is a mass noun)
* Continuity (setting)
A fictional universe, or fictional world, is a self-consistent setting with events, and often other elements, that differ from the real world. It may also be called an imagined, constructed, or fictional realm (or world). Fictional universes may ...

, one of several similar but distinct fictional universes in a broad franchise of related works (this is a count noun)
* "Continuity" or continuity script
''ScreenPlay'' is a television drama anthology series broadcast on BBC2 between 9 July 1986 and 27 October 1993.
Background
