Designing new apartment buildings for strings and conformal field theories. First steps
The concepts of apartments and buildings were suggested by Tits for
description of the Weyl-Coxeter reflection groups. We use these and many
additional facts from the theory of reflection and pseudo-reflection groups
along with results from the algebraic and symplectic geometry of toric
varieties in order to obtain the tachyon-free Veneziano-like multiparticle
scattering amplitudes and the partition function generating these
amplitudes.Although the obtained amplitudes reproduce the tachyon-free spectra
of both open and closed boisonic string, the generating (partition) function is
not that of the traditional bosonic string. It is argued that it is directly
related to the N=2 sypersymmetric quantum mechanical model proposed by Witten
in 1982 in connection with his development of the Morse theory.Such partition
function can be independently obtained with help of the results by Solomon
(published in 1963) on invariants of finite (pseudo) reflection groups.
Although the formalism developed in this work is also applicable to conformal
field theories (CFT), it leaves all CFT results unchangedComment: 90 pages, 2 figures; this version was carefully proofread to

Role of general relativity and quantum mechanics in dynamics of Solar System
Let m(i) be the mass of i-th planet and M be the Solar mass. From
astronomical data it is known that ratios r(i)=m(i)/(m(i)+M) are of order
10^(-3)-10^(-6) for all planets. The same is true for all satellites of heavy
planets. These results suggest that Einstein's treatment of Mercury dynamics
can be extended to almost any object in the Solar System. This fact does not
explain the existing order in the Solar System. Indeed, all planets lie in the
same (Sun's equatorial) plane and move in the same direction coinciding with
that for the rotating Sun.The same is true for regular satellites of heavy
planets and for planetary rings associated with these satellites.In addition to
regular satellites, there are irregular satellites (and at least one irregular
(Saturn) ring associated with such a satellite (Phoebe)) grouped in respective
planes (other than equatorial) in which they all move in "wrong" directions on
stable orbits. These are located strictly outside of those for regular
satellites. This filling pattern is reminiscent to that in atomic mechanics.
Based on the original Heisenberg's ideas, we develop quantum celestial
mechanics explaining this filling pattern and that for rings of heavy planets.
The formalism takes essentially into account that planets and satellites are
moving on geodesics.Comment: 41 page
Heisenberg Honeycombs Solve Veneziano Puzzle
In this paper we reformulate some results obtained by Heisenberg into modern
mathematical language of honeycombs. This language was developed in connection
with complete solution of the Horn conjecture problem. Such a reformulation is
done with the purpose of posing and solving the following problem. Is by
analysing the (spectroscopic) experimental data it possible to restore the
underlying microscopic physical model generating these data? Development of
Heisenberg's ideas happens to be the most useful for this purpose. Solution is
facilitated by our earlier developed string-theoretic formalism. In this paper
only qualitative arguments are presented (with few exceptions). These arguments
provide enough evidence that the underelying microscopic model compatible with
Veneziano-type amplitudes is the standard (i.e. non supersymmetric!) QCD. In
addition, usefulness of the formalism is illustrated on numerous examples such
as physically motivated solution of the saturation conjecture, derivation of
the Yang-Baxter and Knizhnik-Zamolodchikov equations as well as Verlinde and
Hecke algebras, computation of the Gromov-Witten invariants for small quantum
cohomology ring, etc. Finally, we discuss several scattering experiments
testing correctness of our calculations and propose some possible new uses of
these ideas in condensed matter physics.Comment: 61 pages, 16 figure
Veneziano amplitudes, spin chains and Abelian reduction of QCD
Although QCD can be treated perturbatively in the high energy limit, lower
energies requre uses of nonperturbative methods such as ADS/CFT and/or Abelian
reduction.These methods are not equivalent. In this paper we provide arguments
in favor of the Abelian reduction methods. This is achieved by further
developing results of our recent works reanalyzing Veneziano and Veneziano-like
amplitudes and the models associated with these amplitudes. It is shown, that
the obtained new partition function for these amplitudes can be mapped exactly
into that for the Polychronakos-Frahm spin chain model recoverable from the
Richardson-Gaudin XXX spin chain model used originally for treatments of the
BCS-type superconductivity. Because of this, it is demonstrated that the
obtained mapping is compatible with the method of Abelian reduction.Comment: 37 pages, 1 figur
Newtonian limit of Einsteinian gravity: from dynamics of Solar system to dynamics of stars in spiral galaxies
Attempts to merge Einsteinian gravity with Newtonian run into inconsistencies
because in Newton's gravity time is absolute and the speed of gravity is
infinite. Such an assumption was in a focus of attention of scientists in 19th
century interested in finding out if the speed of gravity is infinite. By
analogy with electrodynamics, some retarded potentials replacing Newtonian were
utilized. By using one of such potentials Gerber correctly calculated the
perihelion shift for Mercury in 1902. Subsequent attempts at calculation of
bending of light using Gerber-style calculations were not successful. Recently
Gin\'e (Chaos, Solitons and Fractals 42, 1893 (2009)) reobtained both the
perihelion shift and the bending of light using retarded potential. His
equations however are not those obtained by Einstein and his results coincide
with those by Einstein only at the level of leading order terms of infinite
series expansions. The obtained differential equations of motion are of
delay-type. When applied to two-body dynamics, such equations lead to orbital
quantization. In this work the Einsteinian approach is used to reproduce this
quantization. Numerous arguments justifying the superiority of Einsteinian
approach, including uses of the Bertrand spacetimes for description of motion
of stars around galactic centers are provided. The developed formalism is
tested by calculating the number of allowed stable orbits for planets and those
for regular satellites of heavy planets resulting in reasonable agreement with
observational data. The paper also discusses possible quantum mechanical nature
of rings of heavy planets as well as of rotation curves of stars in spiral
galaxies.Comment: 52 pages. The replacement is rewritten in accord with available

Optical knots and contact geometry I. From Arnol'd inequality to Ranada's dyons
Recently there had been a great deal of activity associated with various
schemes of designing both analytical and experimental methods describing
knotted structures in electrodynamics and in hydrodynamics.The majority of
works in electrodynamics were inspired by the influential paper by Ranada
(1989) and its subsequent refinements. In this work and in its companion we
analyze Ranada's results using methods of contact geometry and topology. Not
only our analysis allows us to reproduce his major results but,in addition, it
provides opportunities for considerably extending the catalog of known knot
types. Furthermore,it allows to reinterpret both the electric and magnetic
charges purely topologically thus opening the possibility of treatment of
masses and charges in Yang-Mills and gravity theories also topologically.
According to(now proven) Thurston's geometrization conjecture complements of
all knots/links in S^3 are spaces of positive, zero or negative curvature. This
means that spaces around our topological masses/charges are also curved. This
fact is essential for design of purely topological theories of gravity,
electromagnetism and strong/weak interactionsComment: 37 page
Optical knots and contact geometry II.From Ranada dyons to transverse and cosmetic knots
Some time ago Ranada (1989) obtained new nontrivial solutions of the
Maxwellian gauge fields without sources. These were reinterpreted in Kholodenko
(2015a) (part I) as particle-like (monopoles, dyons, etc.). They were obtained
by the method of Abelian reduction of the non-Abelian Yang-Mills functional.
The developed method uses instanton-type calculations normally employed for the
non-Abelian gauge fields. By invoking the electric-magnetic duality it then
becomes possible to replace all known charges/masses by the particle -like
solutions of the source-free Abelian gauge fields. To employ these results in
high energy physics, it is essential to to extend Ranada's results by carefully
analysing and classifying all dynamically generated knoted/linked structures in
gauge fields, including those discovered by Ranada. This task is completed in
this work. The study is facilitated by the recent progress made in solving the
Moffatt conjecture. Its essence is stated as follows: in steady incompressible
Euler-type fluids the streamlines could have knots/links of all types. By
employing the correspondence between the ideal hydrodynamics and
electrodynamics discussed in part I and by superimposing it with the already
mentioned method of Abelian reduction, it is demonstrated that in the absence
of boundaries only the iterated torus knots and links could be dynamically
generated. Obtained results allow to develop further particle-knot/link
correspondence studied in Kholodenko (2015b)Comment: 67 pages, 17 figure
New strings for old Veneziano amplitudes IV.Connections with spin chains and other stochastic systems
In a series of published papers we reanalyzed treatments of the Veneziano
amplitudes and the models associated with them. In this work we demonstrate
that the already obtained partition function for these amplitudes can be
exactly mapped into that for the Polychronakos-Frahm spin chain which, in turn,
is obtainable from the Richardson-Gaudin XXX model. Reshetikhin and Varchenko
demonstrated that such a model is recoverable from their WKB-type analysis of
solutions of the Knizhnik-Zamolodchikov (K-Z) equations. The linear
independence of solutions of these equations is controlled by determinants
whose form (up to a constant) coincides with the Veneziano (or Veneziano-like)
amplitudes.In the simplest case, when the K-Z equations are reducible to the
Gauss hypergeometric equation, the determinantal conditions coincide with those
which were discovered by Kummer in 19th century. Kummer's results admit
physical interpretation crucial for providing needed justification associating
determinanatal formula(s) with Veneziano-like amplitudes. General results are
illustrated by many examples. These include but are not limited to only high
energy physics since all high energy physics scattering processes can be looked
upon from much broader sctochastic theory of random fragmentation and
coagulation processes recently undergoing active development in view of its
applications in disciplines ranging from ordering in spin glasses and
population genetics to computer science, linguistics and economics,etc. In this
theory Veneziano amplitudes play the universal role since they are the
Poisson-Dirichlet-type distributions for these processes (analogous to the more
familiar Maxwell distribution for gases)Comment: 66 pages 4 figure
Probabilistic vs optical interpretation of quantum mechanics
Although electrons and photons produce the same interference patterns in the
two-slit experiments, the description of these patters is markedly different.
This difference was analyzed by Bohm. Later on Sanz and Miret-Artes and others
were able to squeeze the differences to zero. Fortunately, they left some room
for developments presented in this Letter. We noticed that in the absence of
sources the electromagnetic field can be represented by the complex scalar
field. It is demonstrated that the same fields are being used in the non
relativistic Schr\"odinger equation. The connection between the electromagnetic
and Schr\"odinger fields allows to study the topology of zero sets (Chladni
patterns) of Schr\"odinger eigenfunctions. The existence of these patterns is
contingent upon the existence of eigenvalues of multiplicity higher than one.
This is permissible only in Schr\"odinger's version of quantum mechanics.
Presence of multiplicities is making quantum mechanical and topological
entanglements equivalent.Comment: 19 page
