#### Numerical **solution** of the Schrödinger equations with polynomial potentials (Part II)

The algorithm of the numerical realization of a fundamental **solution** of a Cauchy problem for the one-dimensional Schrodinger equation with polynomial potentials is described. The stationary Schrodinger equation for a proton in the double potential well is solved by using Ritz variation method. The Green’s function ...

#### The new procedure of receiving the multisoliton **solutions** of the KdV equation

The article offers a new method of obtaining multisoliton **solutions** of KdV equations by means of introducing the characteristic polynomial.
The authors form a representation for multisoliton **solutions** through the second logarithmic derivative of a determinant of a positive-definite matrix.

#### Numerical **solution** of the Schrödinger equations with polynomial potentials (Part I)

The fundamental **solution** of a Cauchy problem and the spectral task for a one-dimensional Schrodinger equations with potential in the form of polynomials m P (x) (m 6) is solved. Numerical calculations are applied to modelling adiabatic potentials with two minima ...

#### Mathematical modeling of the process of attracting customers for paid SAAS **solutions**

The paper considers various aspects of attracting customers to use SaaS solutions from company X. As a test **solution**, an advertising company aimed at the Latin American region was considered. Based on the obtained data, a mathematical model was built that showed the most "weak" points in the advertising company and allowed us to evaluate its effectiveness....

#### The strategic potential of an organisation and the models of programming **solutions** in the conditions of uncertainty

This article considers the problems of studying the strategic potential of organisations in the modern conditions. The authors analyse the methods of allowing for the uncertainty factor within the programming **solution** development procedures.
