Classical electromagnetic potential as a part of gravitational connection: ideas and history

N. V. Kharuk, S. A. Paston, A. A. Sheykin

We consider a natural form of unified theory of gravity and electromagnetism which was somehow missed at the time of intense search for such an unification, and was noticed only in…

Forms of action for perfect fluid in General Relativity and mimetic gravity

S. A. Paston

We consider various forms of action allowing us to describe a perfect fluid in the framework of General Relativity. First we consider a potential motion without pressure. Starting…

Gravitational energy in the framework of embedding and splitting theories

D. A. Grad, R. V. Ilin, S. A. Paston +1

We study various definitions of the gravitational field energy based on the usage of isometric embeddings in the Regge-Teitelboim approach. For the embedding theory we consider the…

Algebra of Implicitly Defined Constraints for Gravity as the General Form of Embedding Theory

S. A. Paston, E. N. Semenova, V. A. Franke +1

We consider the embedding theory, the approach to gravity proposed by Regge and Teitelboim, in which 4D space-time is treated as a surface in high-dimensional flat ambient space. I…

Field-Theoretical Formulation of Regge-Teitelboim Gravity

A. A. Sheykin, S. A. Paston

Theory of gravity is considered in the Regge-Teitelboim approach in which the pseudo-Riemannian space is treated as a surface isometrically embedded in an ambient Minkowski space o…
