The 3+1 decomposition of Conformal Yano-Killing tensors and "momentary" charges for spin-2 field
The "fully charged" spin-2 field solution is presented. This is an analog of
the Coulomb solution in electrodynamics and represents the "non-waving" part of
the spin-2 field theory. Basic facts and definitions of the spin--2 field and
conformal Yano-Killing tensors are introduced. Application of those two objects
provides a precise definition of quasi-local gravitational charge. Next, the
3+1 decomposition leads to the construction of the momentary gravitational
charges on initial surface which is applicable for Schwarzschild-like
spacetimes.Comment: 17 page
Conformal Yano-Killing tensors for space-times with cosmological constant
We present a new method for constructing conformal Yano-Killing tensors in
five-di\-men\-sio\-nal Anti-de Sitter space-time. The found tensors are
represented in two different coordinate systems. We also discuss, in terms of
CYK tensors, global charges which are well defined for asymptotically
(five-dimensional) Anti-de Sitter space-time. Additionally in Appendix we
present our own derivation of conformal Killing one-forms in four-dimensional
Anti-de Sitter space-time as an application of the Theorem presented in the
paper.Comment: 27 page
Simple description of generalized electromagnetic and gravitational hopfions
The generalization of electromagnetic and gravitational hopfions is performed
in terms of a complex scalar field. New definition of topological charge for
linearized gravity is given. Quasi-local (super-)energy densities are compared
for gravitational hopfion.Comment: 27 page
