The field plays here a role of a quintessence field. We consider phase transition in cosmological models of the second and of the first order due to evolution of Higgs' field. We developed inflationary models including calculation of an amount of inflation. We match some cosmological models, calculating a Hubble parameter and an age of the Universe.83 pages, no figuresAstrophysicsCosmological models in the nonsymmetric Kaluza-Klein Theorytext
