Dewitt equation
WebMay 1, 2024 · The equation of Wheeler and DeWitt (WdW) is about the wave function of the universe [19], [20], [21]. It looks similar to the Schrödinger’s equation in one dimension with the important difference that it does not take into account the time evolution. WebMar 3, 2024 · In a theory of quantum gravity, states can be represented as wavefunctionals that assign an amplitude to a given configuration of matter fields and the metric on a spatial slice. These wavefunctionals must obey a set of constraints as a consequence of the diffeomorphism invariance of the theory, the most important of which is known as the …

WebJan 14, 2004 · 1. The WDW equation may be viewed as a kind of schrodinger equation for space, giving it's quantum "evolution" with respect to some "time" parameter. However, unlike in the classical case, different choices of time parameter produce inequivalent theories. The issue then of how a time parameter should be chosen is known as the … WebAug 1, 2024 · DeWitt equation for these two values of the ordering parameter. and compare with the case when p = 0(o r p = 2), in which case. we recover the resu lts known in the literature.
