DESCRIPTION:Speakers: Tatyana Shestakova ()\nThe meaning of the wave funct
 ion of the Universe was actively discussed in 1980s. In most works on quan
 tum cosmology it is accepted that the wave function defines the probabilit
 y amplitude for the Universe to have some space geometry\, or to be found 
 in some point of the Wheeler superspace. It seems that the wave function g
 ives maximally objective description compatible with quantum theory. Howev
 er\, the probability distribution does not depend on time and does not tak
 e into account the existing of our macroscopic evolving Universe. What we 
 wish to know is how quantum processes in the Early Universe determined the
  state of the present Universe in which we are able to observe macroscopic
  consequences of these quantum processes. The picture that can be obtained
  in the Wheeler – DeWitt quantum geometrodynamics is compared with that 
 that of the extended phase space approach to quantization of gravity. We s
 hall discuss how the wave function can be chosen among all possible soluti
 ons of the Wheeler – DeWitt (or Schrödinger) equation\, if it does not 
 depend on a reference frame\, and what stage of the Universe evolution it 
 describes.\n\nhttps://indico.particle.mephi.ru/event/22/contributions/1086
