Singularity

Singularity may refer to any of a variety of concepts.

Mathematics:

* Mathematical singularity, a point at which a given mathematical object is not defined

In complex analysis:

* Essential singularity, a singularity near which a function exhibits extreme behavior
* Isolated singularity, a mathematical singularity that has no other singularities close to it
* Movable singularity, a concept in singularity theory
* Removable singularity, a point at which a function is not defined but at which it can be so defined that it is continuous at the singularity

In algebraic geometry:

* Singular point of an algebraic variety, a point where an algebraic variety is not locally flat
* Rational singularity, a concept in singularity theory
* Singularity theory, which deals with these concepts

Science:

* Gravitational singularity, a point in spacetime in which gravitational forces cause matter to have an infinite density and zero volume
* Mechanical singularity, a position or configuration of a mechanism or a machine where the subsequent behaviour cannot be predicted
* 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
* Technological singularity, a theoretical point in the development of a technological civilization
