This e-book offers an in-depth and rigorous learn of the Wigner rework and its variations. they're provided first inside a context of a normal mathematical framework, after which via functions to quantum mechanics. The Wigner remodel used to be brought by means of Eugene Wigner in 1932 as a chance quasi-distribution which permits expression of quantum mechanical expectation values within the similar shape because the averages of classical statistical mechanics.
