Discrete group of transformations: A group $ \Gamma $ of homeomorphisms of a Hausdorff space $ X $ that satisfies the following condition: It is possible to find neighbourhoods $ U , V $ of arbitrary points $ x , y \in X $ such that the set $$ \{ {\gamma \in \Gamma } : {\gamma ( U) \cap ...

Discrete optimization: Discrete optimization is a branch of optimization in applied mathematics and computer science. As opposed to continuous optimization, some or all of the variables used in a discrete mathematical program are restricted to be discrete variables—that is, to assume ...

Discrete measure: In mathematics, more precisely in measure theory, a measure on the real line is called a discrete measure (in respect to the Lebesgue measure) if it is concentrated on an at most countable set. The support need not be a ... [82%] 2023-06-25 [Measures (measure theory)]
Discrete space: In topology, a discrete space is a particularly simple example of a topological space or similar structure, one in which the points form a discontinuous sequence, meaning they are isolated from each other in a certain sense. The discrete topology ... (Type of topological space) [82%] 2023-10-02 [Topology] [General topology]...
Discrete geometry: Discrete geometry and combinatorial geometry are branches of geometry that study combinatorial properties and constructive methods of discrete geometric objects. Most questions in discrete geometry involve finite or discrete sets of basic geometric objects, such as points, lines, planes, circles ...

Discrete norm: A norm on a skew-field the group of values of which is isomorphic to the group of integers $ \mathbf Z $. In such a case the ring is a discretely-normed ring. (Mathematics) [82%] 2023-12-28
Discrete symmetry: In mathematics and geometry, a discrete symmetry is a symmetry that describes non-continuous changes in a system. For example, a square possesses discrete rotational symmetry, as only rotations by multiples of right angles will preserve the square's original ...

Discrete choice: In economics, discrete choice models, or qualitative choice models, describe, explain, and predict choices between two or more discrete alternatives, such as entering or not entering the labor market, or choosing between modes of transport. Such choices contrast with standard ... (Choice between two or more discrete alternatives) [82%] 2024-02-03 [Choice modelling] [Economics models]...
Discrete space: In topology, a discrete space is a topological space with the discrete topology, in which every subset is open. [82%] 2023-12-28
Discrete transform: In signal processing, discrete transforms are mathematical transforms, often linear transforms, of signals between discrete domains, such as between discrete time and discrete frequency. Many common integral transforms used in signal processing have their discrete counterparts. (Mathematical transform on discrete signals) [82%] 2023-01-19 [Discrete transforms]

Discrete spectrum: A physical quantity is said to have a discrete spectrum if it takes only distinct values, with gaps between one value and the next. The classical example of discrete spectrum (for which the term was first used) is the characteristic ... (Physics) [82%] 2023-12-29 [Spectroscopy] [Physical quantities]...
Discrete analysis: The branch of mathematics whose subject is the study of finite properties of structures which arise both in mathematics itself and in applications. Such finite structures comprise, for example, finite groups (cf. (Mathematics) [82%] 2023-12-28
Discrete metric: The discrete metric on a set is an example of a metric. The discrete metric d on a set X is defined by. [82%] 2023-06-09
Discrete modelling: Discrete modelling is the discrete analogue of continuous modelling. In discrete modelling, formulae are fit to discrete data—data that could potentially take on only a countable set of values, such as the integers, and which are not infinitely divisible.
