Analysis of the equations of motion of fictitious matter in embedding theory
A. J. Ziyatdinov, S. A. Paston
Embedding theory is a possible modification of general relativity that provides a framework for explaining the observed effects typically attributed to dark matter. The idea of thi…
Possible types of dark matter condensation in embedding gravity
S. A. Paston, A. J. Ziyatdinov
We investigate the possibility of explaining the observed effects usually attributed to the existence of dark matter through a transition from GR to a modified theory of gravity -…
Searching for the classical version of Hawking radiation and screening of Coulomb field by the horizon
S. A. Paston, D. S. Shatkov
We investigate the possibility of the existence of a classical version of Hawking radiation - solutions to classical field equations that consist solely of outgoing waves, in the s…
Classification of ten-dimensional symmetric embeddings for the spatially flat Friedman model
M. S. Sushkov, S. A. Paston
All possible variants of symmetric embedding of the metric of the spatially flat Friedman model into a ten-dimensional ambient space are analyzed. It is shown that only two such em…
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…
