Converse of object

• call: The point at which the star's mass is centered is called the singularity.

• have: The problem may have a singularity, or the input may be inappropriate.

• see: See also matrix singularity, matrix inverse, generalized inverse.

Preposition: at

• pole: The price one pays for a general potential, is a singularity at the south pole.

Noun used with modifier

• stress: We apply the method to compressible and incompressible linear elasticity problems, including problems with stress singularities.

• hole: Although computer simulations can help, many algorithms fail when they address regions near black hole singularities where the gravitational fields theoretically approach infinity.

Adjective modifier

• naked: A naked singularity, by contrast, has no such protective barrier.

• absolute: In the absence of any possibility of separating copies from ostensible originals, each thing, in simulation, is thus an absolute singularity.

• initial: But unless one knew what came out of the initial singularity, one could not calculate how the universe would develop.

Modifies a noun

• theorem: The singularity theorems imply the universe had an infinite density at some time in the past.

• theory: Chapter 6 covers singularity theory in the case where there is no distinguished parameter.

• state: Obviously there are a number of degrees of duplication here, and therefore further singularity states.

• analysis: Exact solutions and singularity analysis The Painlevé property has been used in many hundreds of papers to identify integrable cases of equations.

Noun used with modifier

• bang: The scenario for inflation in 1982 was that the universe began with a big bang singularity.

• matrix: See also matrix singularity, matrix inverse, generalized inverse.

Preposition: of

• purpose: With its singularity of purpose and the band's rich and supple performance, this is Carthy's best album to date.
