Is it Possible to Describe Economical Phenomena by Methods of Statistical Physics of Open Systems?
The methods of statistical physics of open systems are used for describing
the time dependence of economic characteristics (income, profit, cost, supply,
currency etc.) and their correlations with each other. Nonlinear equations
(analogies of known reaction-diffusion, kinetic, Langevin equation) describing
appearance of bifurcations, self-sustained oscillational processes,
self-organizations in economic phenomena are offered.Comment: LaTeX, revte
About the Dependence of the Currency Exchange Rate at Time and National Dividend, Investments Size, Difference Between Total Demand and Supply
The time dependence of the currency exchange rate K treated as a function of
national dividend, investments and difference between total demand for a goods
and supply is considered. To do this a proposed earlier general algorithm of
economic processes describing on the basis of the equations for K like the
equations of statistical physics of open systems is used. A number of
differential equations (including nonlinear ones too) determining the time
dependence of the exchange rate (including oscillations) is obtained.Comment: LaTeX, revte
The Multifractal Time and Irreversibility in Dynamic Systems
The irreversibility of the equations of classical dynamics (the Hamilton
equations and the Liouville equation) in the space with multifractal time is
demonstrated. The time is given on multifractal sets with fractional
dimensions. The last depends on densities of Lagrangians in a given time moment
and in a given point of space. After transition to sets of time points with the
integer dimension the obtained equations transfer in the known equations of
classical dynamics. Production of an entropy is not equally to zero in space
with multifractal time, i.e. the classical systems in this space are
non-closed.Comment: RevTe
Does Special Relativity Have Limits of Applicability in the Domain of Very Large Energies?
We have shown in the paper that for time with fractional dimensions
(multifractal time theory) there are small domain of velocities near
where SR must be replaced by fractal theory of almost inertial system that do
not contains an infinity and permits moving with arbitrary velocities.Comment: LaTex, revte
The Theory of Fractal Time: Field Equations (the Theory of Almost Inertial Systems and Modified Lorentz Transformations)
Field equations in four order derivatives with respect to time and space
coordinates based on modified classic relativistic energy of the fractal theory
of time and space are received. It is shown appearing of new spin
characteristics and new fields with imaginary energies .Comment: LaTex2e, revte
Can a Particle's Velocity Exceed the Speed of Light in Empty Space?
Relative motion in space with multifractal time (fractional dimension of time
close to integer ) for "almost"
inertial frames of reference (time is almost homogeneous and almost isotropic)
is considered. Presence in such space of absolute frames of reference and
violation of conservation laws (though, small because of the smallness of
) due to the openness of all physical systems and inhomogeneiy of
time are shown. The total energy of a body moving with is obtained to be
finite and modified Lorentz transformations are formulated. The relation for
the total energy (and the whole theory) reduce to the known formula of the
special relativity in case of transition to the usual time with dimension equal
to one.Comment: RevTeX, 4 page
The Theory of Gravitation in the Space - Time with Fractal Dimensions and Modified Lorents Transformations
In the space and the time with a fractional dimensions the Lorents
transformations fulfill only as a good approach and become exact only when
dimensions are integer. So the principle of relativity (it is exact when
dimensions are integer) may be treated also as a good approximation and may
remain valid (but modified) in case of small fractional corrections to integer
dimensions of time and space. In this paper presented the gravitation field
theory in the fractal time and space (based on the fractal theory of time and
space developed by author early). In the theory are taken into account the
alteration of Lorents transformations for case including and are
described the real gravitational fields with spin equal 2 in the fractal time
defined on the Riemann or Minkowski measure carrier. In the theory introduced
the new "quasi-spin", given four equations for gravitational fields (with
different "quasi spins" and real and imaginary energies). For integer
dimensions the theory coincide with Einstein GR or Logunov- Mestvirichvili
gravitation theory.Comment: LaTex,revte
Why We Can Not Walk To and Fro in Time as Do it in Space? (Why the Arrow of Time is Exists?)
Existence of arrow of time in our world may be easy explained if time has
multifractal nature. The interpretation of nature of time arrow is made on the
base of multifractal theory of time and space presented at works
\cite{kob1}-\cite{kob15}. In this paper shown possibility to walk to and fro in
space and necessity of huge amount of energy for stopping time and changing
direction of it in microscopic volumes.

How Much Energy Have Real Fields Time and Space in Multifractal Universe?
On the base of multifractal theory of time and space (see
\cite{kob1}-\cite{kob16}) in this paper shown presence in every space and time
volumes of real space and time fields a huge supply of energy . In the
multifractal Universe every space volume or time interval possesses by huge
amount of energy() and we discuss the problem is it possible
this new for mankind sorts of energy to extract.

Do Gravitational and Electromagnetic Fields Have Rest Masses in the Fractal Universe?
As well known rest masses of elementary particles and physical fields appear
when temperature of Universe become low enough and symmetry broke. Are there
another sources of rest masses that are consequences of other nature of rest
masses or it is the only methods for generating rest masses? What will be with
massless fields when the laws of symmetry are not exact laws but only are very
good approximation and the time is not homogeneous, as it is in the fractal
world? In this paper based on the fractal theory of time and space (developed
by author earlier) a possible source of rest masses caused by the fractional
dimensions (FD) of the time is considered. It gives rest masses (very small)
for all particles and fields including gravitational and electromagnetic
fields. The estimation of the values of the rest masses gives
, where
is the necessary time for photons and gravitons with rest masses
and to get the velocity equal the speed of light (in the
fractal Universe the moving with any velocities is possible), is the
time of existence of Universe. Under some assumption preliminary values of rest
masses photons and gravitons are obtained: for a rest mass of photons , for a rest mass of gravitons .Comment: LaTex,revtex,5 page
