Established that for n = 4 and n ≥ 7 group G(n) = < a,b;a^n = 1,ab = b³a³> are infinite, and for the remaining n evaluated the procedure and investigate the structure of the group G(n).
In this paper the existence and uniqueness of the solution of the non-local boundary value problem for the mixed type equation in unbounded domain are proved.In this paper the existence and uniqueness of the solution of the non-local boundary value problem for the mixed type equation in unbounded domain are proved.
The differential equation of a fractional order of 0 < β < 1 is considered. Green’s function for such equation is constructed and is shown that in a case β = 1 the found decision passes in earlier known classical decision.
The system of own solenoidal fields of operator Laplace which can be used for decomposition of a geomagnetic field in a kernel of the Earth is described. Boundary conditions provide continuous transition of a field in a referential geomagnetic field.
Mathematical modeling of dynamics of a flexible thread is spent. The technique which
reduces an initial problem about dynamics of a flexible thread to a problem supposing
simple realization for numerical algorithms is offered.
We consider a mathematical model for unsteady transport of radon from the constant coefficients in the soil – atmosphere. An explicit analytical solution for this model and built at different times of his profiles.
In article SAR, InSAR, D-InSAR methods are represented. Program ROI_PAC of interferometry processing is discussed. There are some basic links for investigation of InSAR.
This paper is devoted to the results of using related time series segmentation method based on Grager test to the radon volumetric activity and atmosphere pressure signals.
The general regularities detecting in the psychological development of person is modern
theoretical problem of psychology. So the computer-aided informational system was made as the psychological item for the resolving of this problem. The system stores empirical data, makes processing and generalization of the results, creates the new psychological tests and compares the results in Kamchatka region with other regions’ results by the identical parameters
