A new method of construction of integral varieties of Einstein equations in
three dimensional (3D) and 4D gravity is presented whereby, under corresponding
redefinition of physical values with respect to anholonomic frames of reference
with associated nonlinear connections, the structure of gravity field equations
is substantially simplified. It is shown that there are 4D solutions of
Einstein equations which are constructed as nonlinear superpositions of soliton
solutions of 2D (pseudo) Euclidean sine-Gordon equations (or of Lorentzian
black holes in Jackiw-Teitelboim dilaton gravity). The Belinski-Zakharov-Meison
solitons for vacuum gravitational field equations are generalized to various
cases of two and three coordinate dependencies, local anisotropy and matter
sources. The general framework of this study is based on investigation of
anholonomic soliton-dilaton black hole structures in general relativity. We
prove that there are possible static and dynamical black hole, black torus and
disk/cylinder like solutions (of non-vacuum gravitational field equations) with
horizons being parametrized by hypersurface equations of rotation ellipsoid,
torus, cylinder and another type configurations. Solutions describing locally
anisotropic variants of the Schwarzschild-- Kerr (black hole), Weyl
(cylindrical symmetry) and Neugebauer--Meinel (disk) solutions with anisotropic
variable masses, distributions of matter and interaction constants are shown to
be contained in Einstein's gravity. It is demonstrated in which manner locally
anisotropic multi-soliton-- dilaton-black hole type solutions can be generated.Comment: revtex, twocolumns, 24 pages, version 3 with minor correction
