construction of vector fields with positive lyapunov exponents

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

Effect of Massive Fields on Inflation

Effects caused by an additional massive scalar field interacting with an inflaton field are analyzed. Inflation is shown to have two stages, the first of which is dominant and characterized by ultraslow dynamics of the inflaton field. Constraints on the model parameters are obtained. The occurrence of inflationary era in the universe evolution seems to be inevitable because it allows the explan...

Hamiltonian quantization of effective Lagrangians with massive vector fields.

Effective Lagrangians containing arbitrary interactions of massive vector fields are quantized within the Hamiltonian path integral formalism. It is proven that correct Hamiltonian quantization of these models yields the same result as naive Lagrangian quantization (Matthews’s theorem). This theorem holds for models without gauge freedom as well as for (linearly or nonlinearly realized) spontan...

Five-dimensional Massive Vector Fields and Radion Stabilization

We provide a description of the five-dimensional Higgs mechanism in supersymmetric gauge theories compactified on the orbifold S/Z2 by means of the N = 1 superfield formalism. Goldstone bosons absorbed by vector multiplets can come either from hypermultiplets or from gauge multiplets of opposite parity (Hosotani mechanism). Supersymmetry is broken by the Scherk-Schwarz mechanism. In the presenc...

Gupta-Bleuler quantization for massive and massless free vector fields

It is shown that the usual quantum field theory leads to an ultraviolet divergence in the vacuum energies and an infrared divergence in the two-point functions of the massive and massless vector fields. Using a new method of quantization it is shown that the vacuum energies converge, and the normal ordering procedure is not necessary. Also the propagators are calculated, which are automatically...
