Asymptotic estimates for the solution of the initial jump restoration problem// Journal of Applied Mathematics. In this paper we construct a general boundary value solution of the singularly perturbed problem for a third-order differential equation in the case with stable condition. Using the initial and boundary functions introduced, an analytical representation of the solution to the perturbed problem was found.
Asymptotic estimates of a boundary value solution of the problem have been established, formulas for boundary jumps, jump orders have been found. Limiting transition solution issues have been proven. of the perturbed problem in the solution of the unperturbed problem, the existence of the boundary jump phenomenon in aspiration the small parameter approaches zero. We give the weaknesses identified as: .in the program preferential preference to the general pedagogical issues of the organization of the educational process; insufficiently covered in the program the specifics of teaching mathematics in primary school;
It does not reveal the content of teaching mathematics subjects for high school students; not clearly defined "System Learning Objectives"; mixed text learning objectives, methodical recommendations and recommended exercises for achieving the goal. Keywords: mathematics in primary school, updated mathematics curriculum, system of learning objectives, content of the subject "Mathematics". In this paper, we consider a two-dimensional inverse problem for a hyperbolic equation to restore the source of more information about the solution of the direct problem.
The formulation of the immediate problem is given, where one of the primary conditions is the Dirac delta function. Keywords: hyperbolic equation, two-dimensional coefficient inverse problems, Gelfand-Leitan method, Fredholm equation of the first kind, the Landweber iteration, the Lavrentiev regularization method, the regulation parameter, Heaviside step function, Dirac delta function. In this paper, we consider the spectral adjustment option and recovery techniques of the second-order differential equation by its spectral function.
Solving this inverse problem reduces to solving a linear integral equation called the Gelfand-Levitan equation. For multidimensional implementations, attention should be paid to the approach to determining the coefficient of the wave equation found in M.I. Thus, for the solution of the direct problem in the class of generalized functions, we have the Goursat problem (1), (8), which defines the classical solution of problems (1), (2) and (3) (Figure 1).

The results of the existence of essential patterns of such fragments and their connection with its center. For the description of the extended destruction process, models are used taking into account the statistical nature of the lifetime. The variation of experimental data is explained by the existence for each material of the measure of stability.
In order to develop mental activity, it is necessary to teach students to use their knowledge and skills. According to the modern times, one of the ways of training and knowledge of students is to use modern devices. The paper provides an analysis of some issues of the theory and practice of heat and mass transfer in capillary-porous materials during physico-chemical transformations that occur in the process of structure formation.
Based on the fundamentals of the thermodynamics of irreversible processes [1-3], the following system of equations can be used for the mathematical description of the complicated heat and mass transfer processes that occur concurrently in capillary porous materials:. In real cases, these overlapping transfer processes can proceed in the same or opposite directions, and this determines the signs of the processes accordingly.
