  2. 1. The Quest for M-theory

    Author : Ulf Gran; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; solitons; gauge symmetry; M-theory; string theory; duality; p-branes; D-branes; superspace; supergravity;

    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

  4. 2. From Branes to Brains : On M-theory and Understanding Thermodynamics

    Author : Tom W. Adawi; Jon Ogborn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; M-theory; p-branes; supersymmetry; duality; heat and temperature; phenomenography; context; Physics Education Research; Fysik; Fysikens didaktik; Physics; Fysik; Materiefysik; Physics of Matter; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    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

  5. 3. Exceptional Lie algebras and M-theory

    Author : Jakob Palmkvist; Marc Henneaux; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  6. 4. Aspects of M-theory. Supergravity, duality and noncommutativity

    Author : Henric Larsson; Göteborgs universitet; []

  7. 5. Aspects of Wrapped Branes in String and M-Theory

    Author : Ling Bao; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Instantons; Algebraic symmetries; String theory;

    Abstract : 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. READ MORE
