Mathematical singularity, 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 parameterSingular point of an algebraic variety, a point where an algebraic variety is not locally flatRational singularity, a concept in singularity theorySingularity theory, which deals with these concepts
Complex analysis
Essential singularity, a singularity near which a function exhibits extreme behaviorIsolated singularity, a mathematical singularity that has no other singularities close to itMovable singularity, a concept in singularity theoryRemovable 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
Natural sciences
Gravitational singularity, a point in spacetime in which gravitational forces cause matter to have an infinite density and zero volumeMechanical singularity, a position or configuration of a mechanism or a machine where the subsequent behavior cannot be predictedPenrose–Hawking singularity theorems, theorems in general relativity theory about when gravitation produces singularities such as black holesPrandtl–Glauert singularity, the point at which a sudden drop in air pressure occursSingularity (climate), a weather phenomenon associated with a specific calendar dateVan Hove singularity in the density of states of a material
