What may come beyond the Wheeler-DeWitt approach?

T. P. Shestakova

The goal of this paper is to compare the Wheeler-DeWitt approach, understood in a broad sense, with an alternative one, the so-called extended phase space approach to quantization…

The semiclassical limit of quantum gravity and the problem of time

R. I. Ayala Oña, M. B. Kalmykov, D. P. Kislyakova +1

The question about the appearance of time in the semiclassical limit of quantum gravity continues to be discussed in the literature. It is believed that a temporal Schrodinger equa…

The birth of the Universe as a result of the change of the metric signature

T. P. Shestakova

In this paper, I discuss the idea that the birth of our Universe may be a result of a quantum transition from a physical continuum with the Euclidean signature to a Lorentzian spac…

On A. D. Sakharov's hypothesis of cosmological transitions with changes in the signature of the metric

T. P. Shestakova

I discuss possible consequences of A. D. Sakharov's hypothesis of cosmological transitions with changes in the signature of the metric, based on the path integral approach. This hy…

Wave function of the Universe, path integrals and gauge invariance

T. P. Shestakova

The paper is devoted to some of the difficulties which the Wheeler - DeWitt quantum geometrodynamics encountered, in particular, a strong mathematical proof that this theory is gau…

On the meaning of the wave function of the Universe

T. P. Shestakova

The meaning of the wave function of the Universe was actively discussed in 1980s. In most works on quantum cosmology it is accepted that the wave function is a probability amplitud…
