1. The Quest for M-theory
Sammanfattning : 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. LÄS MER
2. From Branes to Brains : On M-theory and Understanding Thermodynamics
Sammanfattning : 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. LÄS MER
3. Exceptional Lie algebras and M-theory
Sammanfattning : In this thesis we study algebraic structures in M-theory, in particular the exceptional Lie algebras arising in dimensional reduction of its low energy limit, eleven-dimensional supergravity. We focus on e8 and its infinite-dimensional extensions e9 and e10. LÄS MER
4. Aspects of M-theory. Supergravity, duality and noncommutativity
Sammanfattning : .... LÄS MER
5. Aspects of Wrapped Branes in String and M-Theory
Sammanfattning : This thesis consists of an introductory text together with five appended research papers. The Ariadne's thread through the whole thesis is various effects coming from high-dimensional p-branes in various subsectors of string and M-theory. LÄS MER
