DESCRIPTION:Speakers: Elena Arbuzova (Dubna State University and Novosibir
 sk State University)\nA dynamical mechanism for vacuum energy compensation
  in both de Sitter (dS) and anti-de Sitter (AdS) space-times is discussed.
  The proposed cosmological model relies on a non-minimal coupling between 
 a scalar field and the curvature scalar. We demonstrate that this mechanis
 m efficiently eliminates huge initial vacuum energies (both positive and n
 egative)\, dynamically driving the curvature scalar down to zero. In both 
 cases\, the universe enters a power-law expansion regime typical for a cos
 mology dominated by relativistic matter.\n\nhttps://indico.particle.mephi.
