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...
15 صفحه اولMulti - resolution Modeling of Discrete Scalar Fields
Thanks to improvement in simulation, high resolution scanning facilities and multidimensional medical imaging, the size of geometrical dataset is rapidly increasing, and huge datasets are commonly available. The purpose of this thesis is dealing with large sets of twoor three-dimensional discrete data sets describing scalar fields, by using a multiresolution approach. Specifically our aim is in...
متن کاملUnitary Positive-Energy Representations of Scalar Bilocal Quantum Fields
The superselection sectors of two classes of scalar bilocal quantum fields in D ≥ 4 dimensions (whose correlations exhibit minimal singularities) are explicitly determined by working out the constraints imposed by unitarity. The resulting classification in terms of the dual of the respective gauge groups U(N) and O(N) confirms the expectations based on general results obtained in the framework ...
متن کاملQuintessence with Coupled Scalar Fields
We discuss the dynamics of a quintessence model involving two coupled scalar fields. The model presents two types of solutions, namely solutions that correspond to eternal and transient acceleration of the universe. In both cases, we obtain values for the cosmological parameters that satisfy current observational bounds as well as the nucleosynthesis constraint on the quintessence energy density.
متن کاملBoundary Conditions as Mass Generation Mechanism for Complex Scalar Fields
We consider the effects of homogeneous Dirichlet’s boundary conditions in the scalar electrodynamics with self-interaction. We have found for a critical scale of the compactification length that symmetry is restored and scalar field develops mass and vector field does not. PACS numbers: 11.10 Gh, 11.90+t, 03.70+k, 02.90
