| Popis: | This thesis refers to a symmetry-broken scalar-tensor theory with the Higgs field as scalar field, following the Jordan-Brans-Dicke theories and the thoughts of Zee to contribute to solve open problems of cosmology with aid of Higgs gravitation. The Higgs Scalar-Tensor Theory (HSTT) is introduced and examined for spherical symmetry, for spiral galaxies with homogeneous and polytropic density distributions. Flat rotation curves are achieved without assuming Dark Matter. For the case of homogeneous spheres only assuming the existence of a singular central mass for the galaxies; for polytropic spheres, this mass can be neglected. The theory is examined for the Friedmann-Robertson-Walker metric as well, with the result that the Higgs field, as quintessence and massive Inflaton field, leads the inflation of the early universe. This can be New Inflation or Chaotic Inflation, within a breathing universe possibly without an initial singularity. |
