1. Strings, Branes and Symmetries
Abstract : Recent dramatic progress in the understanding of the non-perturbative structure of superstring theory shows that extended objects of various kinds, collectively referred to as p-branes, are an integral part of the theory. In this thesis, comprising an introductory text divided in two parts and seven appended research papers (Papers I-VII), we study various aspects of p-branes with relevance for superstring theory.

2. From Branes to Brains : On M-theory and Understanding Thermodynamics
Abstract : This thesis is concerned with research in both physics and physics education, and is divided into two parts.Part IString theory has been the leading candidate over the past few years for a theory that unifies all the fundamental forces of nature. READ MORE

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

4. The Quest for M-theory
Abstract : In ten dimensions, there exist five consistent string theories and in eleven dimensions there is a unique supergravity theory. When trying to find the fundamental theory of nature this is clearly an "embarrassment of riches". In the mid 90s, however, it was discovered that these theories are all related via a kind of transformation called duality. READ MORE
