Singularity or singular point may refer to:

Science, technology, and mathematics

Mathematics

Mathematical singularity In mathematics, a singularity is a point at which a given mathematical object is not defined, or a point where the mathematical object ceases to be well-behaved in some particular way, such as by lacking differentiability or analyticity. For ex ...

, a point at which a given mathematical object is not defined or not "well-behaved", for example infinite or not differentiable

Geometry

* Singular point of a curve, where the curve is not given by a smooth embedding of a parameter *

Singular point of an algebraic variety In the mathematical field of algebraic geometry, a singular point of an algebraic variety is a point that is 'special' (so, singular), in the geometric sense that at this point the tangent space at the variety may not be regularly defined. In c ...

, a point where an algebraic variety is not locally flat * Rational singularity

Complex analysis

Essential singularity In complex analysis, an essential singularity of a function is a "severe" singularity near which the function exhibits odd behavior. The category ''essential singularity'' is a "left-over" or default group of isolated singularities that a ...

, a singularity near which a function exhibits extreme behaviour * Isolated singularity, a mathematical singularity that has no other singularities close to it * Movable singularity, a concept in singularity theory *

Removable singularity In complex analysis, a removable singularity of a holomorphic function is a point at which the function is undefined, but it is possible to redefine the function at that point in such a way that the resulting function is regular in a neighbourh ...

, a point at which a function is not defined but at which it can be so defined that it is continuous at the singularity

Natural sciences

Singularity (system theory) In the study of unstable systems, James Clerk Maxwell in 1873 was the first to use the term singularity in its most general sense: that in which it refers to ''contexts in which arbitrarily small changes, commonly unpredictably, may lead to arbit ...

, in dynamical and social systems, a context in which a small change can cause a large effect *

Gravitational singularity A gravitational singularity, spacetime singularity or simply singularity is a condition in which gravity is so intense that spacetime itself breaks down catastrophically. As such, a singularity is by definition no longer part of the regular sp ...

, in general relativity, a point in which gravity is so intense that spacetime itself becomes ill defined **

Initial singularity The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe. The instant immediately following the initial ...

, a hypothesized singularity of infinite density before quantum fluctuations caused the Big Bang and subsequent inflation that created the Universe *

Penrose–Hawking singularity theorems The Penrose–Hawking singularity theorems (after Roger Penrose and Stephen Hawking) are a set of results in general relativity that attempt to answer the question of when gravitation produces singularities. The Penrose singularity theorem is ...

, in general relativity theory, theorems about how gravitation produces singularities such as in black holes * Prandtl–Glauert singularity, the point at which a sudden drop in air pressure occurs * Singularity (climate), a weather phenomenon associated with a specific calendar date * Van Hove singularity in the density of states of a material

Technology

Singularity (operating system) Singularity is an experimental operating system developed by Microsoft Research between July 9, 2003, and February 7, 2015. It was designed as a high dependability OS in which the kernel, device drivers, and application software were all written ...

, an operating system developed by Microsoft Research written in managed code * Mechanical singularity, a position or configuration of a mechanism or a machine where the subsequent behavior cannot be predicted *

Singularity (software) Singularity is a free and open-source computer program that performs operating-system-level virtualization also known as containerization. One of the main uses of Singularity is to bring containers and reproducibility to scientific computing a ...

, a container technology that does not require root permissions to run

Futurology

Technological singularity The technological singularity—or simply the singularity—is a hypothetical future point in time at which technological growth becomes uncontrollable and irreversible, resulting in unforeseeable changes to human civilization. According to the m ...
