Sommario/riassunto |

For a long time now it has been common understanding that Africa played only a marginal role in the First World War. Its reduced theatre of operations appeared irrelevant to the strategic balance of the major powers. This volume is a contribution to the growing body of historical literature that explores the global and social history of the First World War. It questions the supposedly marginal role of Africa during the Great War with a special focus on Northeast Africa. In fact, between 1911 and 1924 a series of influential political and social upheavals took place in the vast expanse between Tripoli and Addis Ababa. The First World War was to profoundly change the local balance of power. This volume consists of fifteen chapters divided into three sections. The essays examine the social, political and operational course of the war and assess its consequences in a region straddling Africa and the Middle East. The relationship between local events and global processes is explored, together with the regional protagonists and their agency. Contrary to the myth still prevailing, the First World War did have both immediate and long-term effects on the region. This book highlights some of the significant aspects associated with it. |

Sommario/riassunto |
|
This monograph aims to provide a unified, geometrical foundation of gauge theories of elementary particle physics. The underlying geometrical structure is unfolded in a coordinate-free manner via the modern mathematical notions of fibre bundles and exterior forms. Topics such as the dynamics of Yang-Mills theories, instanton solutions and topological invariants are included. By transferring these concepts |

to local space-time symmetries, generalizations of Einstein's theory of gravity arise in a Riemann-Cartan space with curvature and torsion. It provides the framework in which the (broken) Poincaré gauge theory, the Rainich geometrization of the Einstein-Maxwell system, and higher-dimensional, non-abelian Kaluza-Klein theories are developed. Since the discovery of the Higgs boson, concepts of spontaneous symmetry breaking in gravity have come again into focus, and, in this revised edition, these will be exposed in geometric terms. Quantizing gravity remains an open issue: formulating it as a de Sitter type gauge theory in the spirit of Yang-Mills, some new progress in its topological form is presented. After symmetry breaking, Einstein’s standard general relativity with cosmological constant emerges as a classical background. The geometrical structure of BRST quantization with non-propagating topological ghosts is developed in some detail. |
