Qué (quién) es K-transform - definición
K-transform
In mathematics, the K transform (also called the Kemp-Macdonald Transform or Single-Pixel X-ray Transform) is an integral transform introduced by R. Scott Kemp and Ruaridh Macdonald in 2016.
Z-transform
MATHEMATICAL TRANSFORM WHICH CONVERTS SIGNALS FROM THE TIME DOMAIN TO THE FREQUENCY DOMAIN
Z transform; Laurent transform; Bilateral Z-transform; Bilateral z-transform; Z Transform; Z-domain; Z-transformation
In mathematics and signal processing, the Z-transform converts a discrete-time signal, which is a sequence of real or complex numbers, into a complex frequency-domain (z-domain or z-plane) representation.
Penrose transform
COMPLEX ANALOGUE OF THE RADON TRANSFORM THAT RELATES MASSLESS FIELDS ON SPACETIME TO COHOMOLOGY OF SHEAVES ON COMPLEX PROJECTIVE SPACE
Penrose-Ward transform; Ward transform; Penrose–Ward transform; Ward correspondence; Twistor transform
In theoretical physics, the Penrose transform, introduced by , is a complex analogue of the Radon transform that relates massless fields on spacetime to cohomology of sheaves on complex projective space. The projective space in question is the twistor space, a geometrical space naturally associated to the original spacetime, and the twistor transform is also geometrically natural in the sense of integral geometry.
