Sommario/riassunto

This book presents a review of various issues related to Lorentz symmetry breaking. Explicitly, we consider (i) motivations for introducing Lorentz symmetry breaking, (ii) classical aspects of Lorentz-breaking field theory models including typical forms of Lorentz-breaking additive terms, wave propagation in Lorentz-breaking theories, and mechanisms for breaking the Lorentz symmetry; (iii) quantum corrections in Lorentz-breaking theories, especially the possibilities for perturbation generating the most interesting Lorentz-breaking terms; (iv) correspondence between non-commutative field theories and Lorentz symmetry breaking; (v) supersymmetric Lorentz-breaking theories; and (vi) Lorentz symmetry breaking in a curved space-time. We close the book with the review of experimental studies of Lorentz symmetry breaking. The importance and relevance of these topics are explained, first, by studies of limits of applicability of the Lorentz symmetry, second, by searches of the possible extensions of the standard model, including the Lorentz-breaking ones, and need to study their properties, third, by the relation between Lorentz symmetry breaking with string theory, fourth, by the problem of formulating a



consistent quantum gravity theory, so that various modified gravity models are to be examined.

Sommario/riassunto

Oil is the world's single most important commodity and its political effects are pervasive. Jeff Colgan extends the idea of the resource curse into the realm of international relations, exploring how countries form



their foreign policy preferences and intentions. Why are some but not all oil-exporting 'petrostates' aggressive? To answer this question, a theory of aggressive foreign policy preferences is developed and then tested, using both quantitative and qualitative methods. Petro-Aggression shows that oil creates incentives that increase a petrostate's aggression, but also incentives for the opposite. The net effect depends critically on its domestic politics, especially the preferences of its leader. Revolutionary leaders are especially significant. Using case studies including Iraq, Iran, Libya, Saudi Arabia and Venezuela, this book offers new insight into why oil politics has a central role in global peace and conflict.
