Wigner distribution
From Biocrawler, the free encyclopedia.
The Wigner distribution is either of two things:
- Wigner semicircle distribution - A probability function used in mathematics (Eugene Wigner)
- Wigner quasi-probability distribution - Originally this was a representation of the wave-function in quantum physics. It is also known as the Wigner-Weyl transformation since it is the Weyl symbol for the density matrix. In signal analysis it is known as the Wigner-Ville distribution. It is used in statistical mechanics, quantum chemistry, optics, etc. (Eugene Wigner, Hermann Weyl, J. Ville)
