1. Wave interactions by Hamiltonian methods
Sammanfattning : This thesis is devoted to the description of fluids and gases from a Hamiltonian point of view. The method we apply is a development of the theory invented by Hamilton (1805-1865). The original formulation is restricted to a certain family of dynamical variables; the canonical variables. LÄS MER
2. Linking Probability Theory and Quantum Mechanics, and a Novel Formulation of Quantization
Sammanfattning : This doctoral thesis in mathematics consists of three articles that explore the probabilistic structure of quantum mechanics and quantization from a novel perspective.The thesis adopts a probabilistic interpretation of quantum mechanics, which views the archetypical quantum experiments of Bell- and double-slit- type as violating the principle of non-contextuality, i.

3. Yang-Mills Theory in Gauge-Invariant Variables and Geometric Formulation of Quantum Field Theories
Sammanfattning : In Part I we are dealing with effective description of Yang-Mills theories based on gauge-invarint variables. For pure Yang-Mills we study the spin-charge separation varibles. The dynamics in these variables resembles the Skyrme-Faddeev model. LÄS MER
4. Rotational effects in water waves
Sammanfattning : Abstract: This thesis consists of four papers related to various aspects of water waves with vorticity. Paper I: Symmetry of steady periodic gravity water waves with vorticity. LÄS MER
5. Strings as Sigma Models and in the Tensionless Limit
Sammanfattning : This thesis considers two different aspects of string theory, the tensionless limit of the string and supersymmetric sigma models with extended supersymmetry. First, the tensionless limit is used to find a IIB supergravity background generated by a tensionless string. The background has the characteristics of a gravitational shock-wave. LÄS MER
