Gauge generator for bi-gravity and multi-gravity models

چکیده
Following the Hamiltonian structure of bi-gravity and multi-gravity models in full phase space, we have constructed generating functional diffeomorphism gauge symmetry. As is expected, this generator from first class constraints system. We show that works well giving transformations canonical variables.

Matrix Models , Emergent Gravity , and Gauge Theory
Matrix models of Yang-Mills type induce an effective gravity theory on 4-dimensional branes, which are considered as models for dynamical space-time. We review recent progress in the understanding of this emergent gravity. The metric is not fundamental but arises effectively in the semi-classical limit, along with nonabelian gauge fields. This leads to a mechanism for protecting certain geometr...
متن کاملDualities and Emergent Gravity: Gauge/Gravity Duality
In this paper I develop a framework for relating dualities and emergence: two notions that are close to each other but also exclude one another. I adopt the conception of duality as ‘isomorphism’, from the physics literature, cashing it out in terms of three conditions. These three conditions prompt two conceptually different ways in which a duality can be modified to make room for emergence; a...
متن کاملGauge Fields and Gravity
The work extends the A. Connes’ noncommutative geometry to spaces with generic local anisotropy. We apply the E. Cartan’s anholonomic frame approach to geometry models and physical theories and develop the nonlinear connection formalism for projective module spaces. Examples of noncommutative generation of anholonomic Riemann, Finsler and Lagrange spaces are analyzed. We also present a research...
متن کاملGravity and Gauge Theory∗
Gauge theories are theories that are invariant under a characteristic group of gauge transformations. General relativity is invariant under transformations of the diffeomorphism group. This has prompted many philosophers and physicists to treat general relativity as a gauge theory, and diffeomorphisms as gauge transformations. I argue that this approach is misguided. The theories of three of ...
متن کاملGauge/gravity duality
We review the emergence of gravity from gauge theory in the context of AdS/CFT duality. We discuss the evidence for the duality, its lessons for gravitational physics, generalizations, and open questions.
