DESCRIPTION:Speakers: Pavel Korolyov (PFUR\,)\nWe consider 6D manifolds wi
 th the structure M0 x M1 x  M2\, where M0 is 2D Lorentzian space-time whil
 e each of M1 and M2 can be a 2-sphere or a 2-torus.Among such geometries\,
  we find examples of regular solutions of 6D general relativity with a sca
 lar field as a source of gravity\, which depend on a single coordinate x r
 anging over the whole real axis\, with different asymptotic behavior at pl
 us and minus infinity. On one end\, it is a 4D de Sitter universe times sm
 all extra dimensions\, while on the other end there is some kind of a stat
 ic space-time. We thus obtain configurations called black universes\, look
 ing as a black hole on the static end and as an expanding universe on the 
 other\, and the cosmological expansion begins from a horizon.\n\nhttps://i
