Renormalization by gravity and the Kerr spinning particle
On the basis of the Kerr spinning particle, we show that the mass
renormalization is perfectly performed by gravity for an arbitrary distribution
of source matter. A smooth regularization of the Kerr-Newman solution is
considered, leading to a source in the form of a rotating bag filled by a false
vacuum. It is shown that gravity controls the phase transition to an AdS or dS
false vacuum state inside the bag, providing the mass balance.Comment: 9 pages, 2 figure
Complex Kerr Geometry, Twistors and the Dirac Electron
The Kerr-Newman spinning particle displays some remarkable relations to the
Dirac electron and has a reach spinor structure which is based on a twistorial
description of the Kerr congruence determined by the Kerr theorem. We consider
the relation between this spinor-twistorial structure and spinors of the Dirac
equation, and show that the Dirac equation may naturally be incorporated into
Kerr-Schild formalism as a master equation controlling the twistorial structure
of Kerr geometry. As a result, the Dirac electron acquires an extended
space-time structure having clear coordinate description with natural
incorporation of a gravitational field. The relation between the Dirac wave
function and Kerr geometry is realized via a chain of links: {\it Dirac wave
function Complex Kerr-Newman Source Kerr
Theorem Real Kerr geometry.} As a result, the wave function
acquires the role of an ``order parameter'' which controls spin, dynamics, and
twistorial polarization of Kerr-Newman space-time.Comment: 12 pages, 3 figs. Talk at the conference QFEXT'0
Rotating Black Hole, Twistor-String and Spinning Particle
We discuss basic features of the model of spinning particle based on the Kerr
solution. It contains a very nontrivial {\it real} stringy structure consisting
of the Kerr circular string and an axial stringy system.
We consider also the complex and twistorial structures of the Kerr geometry
and show that there is a {\it complex} twistor-string built of the complex N=2
chiral string with a twistorial structure. By imbedding into the
real Minkowski , the N=2 supersymmetry is partially broken and string
acquires the open ends. Orientifolding this string, we identify the chiral and
antichiral structures. Target space of this string is equivalent to the
Witten's `diagonal' of the Comment: 19 p. 4 figures, extended version of hep-th/0412065, based on the

Kerr-Schild Approach to the Boosted Kerr Solution
Using a complex representation of the Debney-Kerr-Schild (DKS) solutions and
the Kerr theorem we analyze the boosted Kerr geometries and give the exact and
explicit expressions for the metrics, the principal null congruences, the
coordinate systems and the location of the singularities for arbitrary value
and orientation of the boost with respect to the angular momentum. In the
limiting, ultrarelativistic case we obtain light-like solutions possessing
diverging and twisting principal null congruences and having, contrary to the
known pp-wave limiting solutions, a non-zero value of the total angular
momentum. The implications of the above results in various related fields are
discussed.Comment: 16 pages, LaTe
The Newman-Janis Algorithm, Rotating Solutions and Einstein-Born-Infeld Black Holes
A new metric is obtained by applying a complex coordinate trans- formation to
the static metric of the self-gravitating Born-Infeld monopole. The behaviour
of the new metric is typical of a rotating charged source, but this source is
not a spherically symmetric Born-Infeld monopole with rotation. We show that
the structure of the energy-momentum tensor obtained with this new metric does
not correspond to the typical structure of the energy momentum tensor of
Einstein-Born-Infeld theory induced by a rotating spherically symmetric source.
This also show, that the complex coordinate transformations have the
interpretation given by Newman and Janis only in space-time solutions with
linear sources
Algbrodynamics over complex space and phase extension of the Minkowski geometry
First principles should predetermine physical geometry and dynamics both
together. In the "algebrodynamics" they follow solely from the properties of
the biquaternion algebra \B and the analysis over \B. We briefly present
the algebrodynamics on the Minkowski background based on a nonlinear
generalization to \B of the Cauchi-Riemann analyticity conditions. Further,
we consider the effective real geometry uniquely resulting from the structure
of multiplication in \B which turns out to be of the Minkowski type, with an
additional phase invariant. Then we pass to study the primordial dynamics that
takes place in the complex \B space and brings into consideration a number of
remarkable structures: an ensemble of identical correlated matter pre-elements
("duplicons"), caustic-like signals (interaction carriers), a concept of random
complex time resulting in irreversibility of physical time at a macrolevel,
etc. In partucular, the concept of "dimerous electron" naturally arises in the
framework of complex algebrodynamics and, together with the above-mentioned
phase invariant, allows for a novel approach to explanation of quantum
interference phenomena alternative to the recently accepted paradigm of
wave-particle dualism.Comment: 14 pages, twocolum
