Abstract:
Analyticalnon-perturbative study of thethree-dimensional nonlinear stochastic partialdifferential equation
with additive thermal noise, analogous to thatproposed by V.N.Nikolaevskii [1]-[5] to describelongitudinal
seismic waves, ispresented. Theequation has a threshold of short-waveinstability and symmetry, providing
longwavedynamics.New mechanism of quantum chaos generating in nonlineardynamical systemswith
infinite number of degrees of freedom is proposed. The hypothesis is said,that physical turbulence could be
identifiedwith quantum chaos of considered type. It is shown that the additive thermal noise destabilizes
dramatically the ground state of theNikolaevskii system thus causing it to make a direct transition from a
spatially uniform to a turbulent state.

1.Introduction
In the present work a non-perturbative analyticalapproach to the studying of problemof quantum chaos in
dynamical systems withinfinite number of degrees of freedom isproposed.Statistical descriptions of
dynamical chaos and investigations of noise effects on chaoticregimes arestudied.Proposed approach also
allows estimate the influence of additive (thermal)fluctuations on the processes of formation ofdeveloped
turbulence modes in essentially nonlinearprocesses like electro-convection andother. A principal rolethe
influence ofthermalfluctuations on thedynamics of some types of dissipative systems inthe approximate
environs of derivation rapid of ashort-wave instability was ascertained. Impotentphysicalresults follows
from Theorem 2, is illustrated by example of 3D stochastic model system:

Systematic study of a different type of chaos at onset ‘‘soft-mode turbulence’’based onnumerical
integration of the simplest 1DNikolaevskii model (1.7)has been executed by many authors [2]-[7].There is
an erroneous belief that such numerical integration gives a powerful analysisismeans of the processes of
turbulence conception, based on the classical theory ofchaos of the finite-dimensional classical systems
[8]-[11].
Remark1.1.However, as it well known, such approximations correct only in a phase ofturbulence
conception, when relatively small number of the degrees of freedom excites. In general case, when a very
large number of the degrees of freedom excites, well known phenomena of thenumerically induced chaos,
can to spoils in the uncontrollable wayany numerical integration[12]-[15]
Remark1.2.Other non trivial problem stays from noise roundoff error in computer computation using
floatingpoint arithmetic [16]-[20].In any computer simulation the numerical solution is fraught with
truncation by roundoff errors introduced by finite-precision calculation of trajectories of dynamical systems,
where roundoff errors or other noise can introduce new behavior and this problem is a very more
pronounced in the case of chaotic dynamical systems, because the trajectories of such systems
exhibitextensivedependence on initial conditions. As a result, a small random truncation or roundoff error,
made computational error at any step of computation will tend to be large magnified by future
computationalof the system[17].
Remark1.3.As it well known, if the digitized or rounded quantity is allowed to occupy the nearest of a
large number of levels whose smallest separation is 56, then, provided that the
original quantity is large compared to 56 and is reasonably well behaved, theeffect of the quantization or
rounding may betreated as additive random noise [18].Bennett has shown that such additive noise is nearly
white, withmean squared value of 56
/12[19].However the complete uniform white-noise model to be valid
in the sense of weak convergence of probabilistic measures as the lattice step tends to zero if the matrices
of realization of the system in the state space satisfy certain nonresonance conditions and the
finite-dimensional distributions of the input signal are absolutely continuous[19].
The method deprived of these essential lacks in general case has been offered by the author in papers

42. International Journal of Recent advances in Physics (IJRAP) Vol.4, No.1, February 2015
23
[23]-[27].
Remark1.4.Thus from consideration above it is clear thatnumerical integration procedure ofthe1D
Nikolaevskii model (1.6)-(1.7) executed in papers [2]-[7]in fact dealing withstochastic model
(1.4)-(1.5).There is an erroneous the point of view,that a white noise with enough small intensity does not
bringanysignificant contributions in turbulent modes, see for example [3]. By this wrong assumptions the
results of the numerical integration procedure ofthe1D Nikolaevskii model (1.6)-(1.7) were mistakenly
considered and interpretedas a veryexact modeling the slow turbulence within purely non stochastic
Nikolaevskii model (1.6)-(1.7).Accordingly wrongconclusionsabout that temperature noisesdoes not
influence slowturbulence have been proposed in [3].However in [27] has shown non-perturbativelythat that
a white noise with enough small intensity can to bring significant contributions in turbulent modes and
even to change this modes dramatically.
At the present time it is generally recognized thatturbulence in its developed phase has essentiallysingular
spatially-temporal structure. Such asingular conduct is impossible to describeadequately by the means of
some model system of equations of a finite dimensionality. In thispoint a classical theory of chaos is able
todescribe only small part of turbulencephenomenon in liquid and another analogous sof dynamical
systems. The results of non-perturbative modeling ofsuper-chaotic modes, obtained in the present paper
allow us to put out a quite probablehypothesis: developed turbulence in the realphysical systems with
infinite number of degreesof freedom is a quantum super-chaos, at that the quantitative characteristics of
this super-chaos, iscompletely determined by non-perturbativecontribution of additive (thermal)
fluctuations inthe corresponding classical system dynamics [18]-[20].
2.Main Theoretical Results
We study the stochastic 7-dimensionaldifferential equation analogous proposed byNikolaevskii [1] to
describe longitudinal seismicwaves:

The main difficulty with the stochasticNikolaevskii equationis that the solutions do not take values in an
function space but in generalized functionspace. Thus it is necessary to give meaning to the non-linear
terms $B
,
, , 9

53. , , = 1, … , 7 because the usual product makes no sense for arbitrary distributions.
We deal with product of distributions via regularizations, i.e., we approximate the distributions by
appropriate way and pass to the limit.In this paper we use the approximation of the distributions by
approach of Colombeaugeneralized functions [28].

In generally accepted at the present time hypothesiswhatphysical turbulencein the dynamical systems with
an infinite number of degrees of freedom really is, thephysical turbulence is associated with a
strangeattractors, on which the phase trajectories of dynamical system reveal the knownproperties of
stochasticity: a very high dependence on the initial conditions, whichis associated with exponential
dispersion of the initially close trajectories and bringsto their non-reproduction; everywhere the density on

In contrast with canonical numerical simulation, by using Theorem2.1 it is possible to study
non-perturbativelythe influence of thermal additive fluctuationson classical dynamics, which in the

7.Conclusion
A non-perturbative analytical approach to the studying of problemof quantum chaos in dynamical systems
withinfinite number of degrees of freedom isproposed and developed successfully.It is shown that the
additive thermal noise destabilizes dramatically the ground state of the system thus causing it to make a
direct transition from a spatially uniform to a turbulent state.
