Classification of ten-dimensional embeddings of spherically symmetric static metrics
S. S. Kuptsov, S. A. Paston, A. A. Sheykin
The group-theoretic method for constructing symmetric isometric embeddings is used to describe all possible four-dimensional surfaces in flat -dimensional space, whose induc…
Yet another way from field theory to gravity
A. A. Sheykin
It is shown that target space diffeomorphism invariance of a generic Lagrangian for a set of scalar fields leads to an analog of Einstein equations for the geometry of a level set…
Lower-dimensional Regge-Teitelboim gravity
A. A. Sheykin, A. A. Grechko
We study modified gravity theory known as Regge-Teitelboim approach, in which the gravity is represented by dynamics of a surface isometrically embedded in a flat bulk. We obtain s…
Global embedding of BTZ spacetime using generalized method of symmetric embeddings construction
A. A. Sheykin, M. V. Markov, S. A. Paston
It is often easier to study pseudo-Riemannian manifolds by presenting them as surfaces in some ambient space. We propose an algorithm for construction of explicit isometric embeddi…

S. A. Paston, E. N. Semenova, A. A. Sheykin
We consider the approach to gravity in which four-dimensional curved spacetime is represented by a surface in a flat Minkowski space of higher dimension. After a short overview of…

We discuss field theories appearing as a result of applying field transformations with derivatives (differential field transformations, DFT) to a known theory. We begin with some s…
Polyakov-like approach to the modified gravity and other geometric theories
A. A. Sheykin, M. V. Ioffe, S. N. Manida +1
We study the procedure that allows to rewrite the actions of some modified gravity theories like mimetic gravity and Regge-Teitelboim embedding theory as Einstein-Hilbert actions w…

A. A. Sheykin, D. P. Solovyev, S. A. Paston
We study the problem of construction of global isometric embedding for spherically symmetric black holes with negative cosmological constant in various dimensions. Firstly, we show…
Definitions of energy for the description of gravity as the splitting theory
D. A. Grad, S. A. Paston, A. A. Sheykin
We study the definitions of energy, naturally arising in the splitting theory, which is the field theoretic formulation of the Regge-Teitelboim gravity. The latter regards our spac…
Embedding theory as new geometrical mimetic gravity
S. A. Paston, A. A. Sheykin
It is known that recently proposed model of mimetic gravity can be presented as general relativity with an additional mimetic matter. We discuss a possibility to analogously reform…
Description of gravity in the model with independent nonsymmetric connection

A generalization of General Relativity is studied. The standard Einstein-Hilbert action is considered in the Palatini formalism, where the connection and the metric are independent…

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…
