Irrespective Priority-Based Regular Properties of High-Intensity Virtual Environments
We have a lot of relation to the encoding and the Theory of Information, when
considering thinking. This is a natural process and, at once, the complex thing
we investigate. This always was a challenge - to understand how our mind works,
and we are trying to find some universal models for this. A lot of ways have
been considered so far, but we are looking for Something, we seek for
approaches. And the goal is to find a consistent, noncontradictory view, which
should at once be enough flexible in any dimensions to allow to represent
various kinds of processes and environments, matters of different nature and
diverse objects. Developing of such a model is the destination of this article.Comment: 4 pages, 2 figures; ISBN: 978-1-4673-2984-
Scalar-tensor gravity and conformal continuations
Global properties of vacuum static, spherically symmetric configurations are
studied in a general class of scalar-tensor theories (STT) of gravity in
various dimensions. The conformal mapping between the Jordan and Einstein
frames is used as a tool. Necessary and sufficient conditions are found for the
existence of solutions admitting a conformal continuation (CC). The latter
means that a singularity in the Einstein-frame manifold maps to a regular
surface S_(trans) in the Jordan frame, and the solution is then continued
beyond this surface. S_(trans) can be an ordinary regular sphere or a horizon.
In the second case, S_(trans) proves to connect two epochs of a Kantowski-Sachs
type cosmology. It is shown that, in an arbitrary STT, with arbitrary potential
functions , the list of possible types of causal structures of vacuum
space-times is the same as in general relativity with a cosmological constant.
This is true even for conformally continued solutions. It is found that when
S_(trans) is an ordinary sphere, one of the generic structures appearing as a
result of CC is a traversable wormhole. Two explicit examples are presented: a
known solution illustrating the emergence of singularities and wormholes, and a
nonsingular 3-dimensional model with an infinite sequence of CCs.Comment: Latex2e, 13 pages, 3 bezier figure
