Abstract

If gravity arises as a consequence of quantum corrections of gauge theory it is necessary to take into account that the parameter ε{lunate} of a non-minimal coupling of the scalar field ψ with a curvature is the function ε{lunate}(φ{symbol})=η+ [e2/2(4π)2][ln(φ{symbol}22)-3]. The model allows for the chaotic inflation scenario. At η=e2/(4π)2 the rate of decrease of the gravitational constant is |G|/G<eH2/mP; in the postinflation epoch the structure of the theory practically coincides with that of Einstein's general relativity.
