Singularity

Singularity or singular point may refer to:

Science, technology, and mathematics

Mathematics

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

Geometry

• Rational singularity

Complex analysis

• Essential singularity, 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, 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
