| contents | The model of vacuum energy compensation due to interaction of a scalar field $ϕ$ with curvature scalar of the form $βR ϕ^2 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. |
