A mathematical method of converting a particular two-dimensional scalar magnetic field map to a particular two-dimensional vector map.

plural of Holstein-Primakoff transformation

(quantum mechanics) A mapping to the spin operators from boson creation and annihilation operators, effectively truncating their infinite-dimensional Fock space to finite-dimensional subspaces.

(category theory) A natural transformation whose naturality squares are pullbacks.

plural of Cartesian natural transformation

plural of Foldy-Wouthuysen transformation

(geology) A geological fault separating two tectonic plates which are sliding horizontally in directions parallel with the fault line.

(mathematics) an integral transform of positive real function f(t) to a complex function F(s); given by:

(mathematical analysis, harmonic analysis, physics, electrical engineering) A particular integral transform that when applied to a function of time (such as a signal), converts the function to one that plots the original function's frequency composition; the resultant function of such a conversion.

(mathematics) A transform that converts a discrete time-domain signal into a complex frequency-domain representation.
