Abstract

The model of vacuum energy compensation due to interaction of a scalar field ϕ with curvature scalar of the form βR ϕ² f(ϕ) is proposed. It is shown that with a simple power form of f(ϕ) the exponential expansion, induced by vacuum energy (or what is the same by cosmological constant), is transformed into canonical cosmological evolution of the universe dominated by relativistic matter.
