Lorentzian Geometrical Structures with Global Time, Gravity and Electrodynamics - Bog af Arkady Poliakovsky - Hardback

Lorentzian Geometrical Structures with Global Time, Gravity and Electrodynamics - Bog af Arkady Poliakovsky - Hardback

This book investigates Lorentzian structures in the four-dimensional space-time, supplemented either by a covector field of the time-direction or by a scalar field of the global time. Furthermore, it proposes a new metrizable model of gravity. In contrast to the usual General Relativity theory, where all ten components of the symmetric pseudo-metric are independent variables, the gravity model presented here essentially depends only on a single four-covector field, and is restricted to have only..

Isolated Objects in Quadratic Gravity - Samuele Silvervalle

Isolated Objects in Quadratic Gravity - Samuele Silvervalle

One of the main unanswered question of modern Physics is \How does gravity behave at small scales?\. The aim of this thesis is to illustrate in a comprehensive but accessible way how to look for deviations from Einstein's theory of General Relativity in this regime, looking at the simplest celestial bodies: static and spherically symmetric ones.With a conservative and bottom-up approach, at smaller scales the first corrections to the action of General Relativity are generally considered to be terms..

The Art of Gluing Space-Time Manifolds - Reza Mansouri

The Art of Gluing Space-Time Manifolds - Reza Mansouri

This concise book reviews methods used for gluing space-time manifolds together. It is therefore relevant to theorists working on branes, walls, domain walls, concepts frequently used in theoretical cosmology, astrophysics, and gravity theory. Nowadays, applications are also in theoretical condensed matter physics where Riemannian geometry appears. The book also reviews the history of matching conditions between two space-time manifolds from the early times of general relativity up to now.

Landmarks for Spatial Development - Bog af André Torre, Vikas Kumar, mfl. - Hardback

Landmarks for Spatial Development - Bog af André Torre, Vikas Kumar, mfl. - Hardback

The book explores the uneven spatial distribution of territory resources and its implication for the sustainable development of regions and cities. The authors analyze the features of the localization of assets, paying attention to both the manifested factors and the conditions that determine the specificity of the current spatial organization. On the basis of multivariate analysis, gravity models, clustering method, as well as the evaluation of concentration parameters, the authors propose various..

Twistor Sigma Models - Bog af Atul Sharma - Hardback

Twistor Sigma Models - Bog af Atul Sharma - Hardback

In recent decades, twistor theory has grown into an irreplaceable tool for the study of scattering amplitudes in gauge theory and gravity. This book introduces the reader to cutting-edge advances in twistor theory and its applications to general relativity. The problem of graviton scattering in four dimensions is shown to be dual to dramatically simpler computations in a two-dimensional CFT known as a twistor sigma model. Twistor sigma models are the first step toward a holographic description of..
