  1. 1. BRST and Topological Gauge Theories

    Author : Niclas Sandström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gauge theory; BRST-quantization; topological field theory; BV-quantization; almost product structure APS ; superfield formulation;

    Abstract : In this thesis, the BRST-quantization of gauge theories is discussed. A detailed analysis of the BRST-quantization on inner product spaces is performed for a class of abelian models, including reparametrization invariant ones. General rules how to obtain physical wave functions and propagators are proposed. READ MORE

  2. 2. Strings, Branes and Non-trivial Space-times

    Author : Jonas Björnsson; Stephen Hwang; Ioannis Bakas; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; String theory; Membranes; BRST; p -branes; p -branes; Non-compact backgrounds; WZNW-model; No-ghost theorem; Unitarity; Hermitian symmetric spaces; CFT; Physics; Fysik; Physics; Fysik;

    Abstract : This thesis deals with different aspects of string and /p/-brane theories. One of the motivations for string theory is to unify the forces in nature and produce a quantum theory of gravity. /p/-branes and related objects arise in string theory and are related to a non-perturbative definition of the theory.

  3. 3. Derivation and BRST Quantization of Models for Spinning Relativistic Particles

    Author : Ulf Mårtensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis deals with the construction of models for spinning relativistic particles and their covariant quantization within a BRST framework. In the first part the ideas and methods which constitute the background to the papers are reviewed, and a summary of the main results obtained therein is given. The second part consists of the papers. READ MORE
