The article describes general information about one- and two-dimensional simplexes and their properties. In addition, classifications of quadratic operators defined in these simplexes, necessary and sufficient conditions for being surjective and dual, and conditions for being a homeomorphism are given and proved as theorems.

Among practical problems, one of the most topical are problems in which the propagation of wave processes in three-dimensional elastic bodies is considered. Such processes are of great importance in the construction of underground cylindrical structures. They occur during earthquakes and in a number of other cases. The main elements of most structures are cylindrical cavities. Therefore, the study of dynamic processes in such objects is of the greatest interest. This article discusses the development of a numerical algorithm for studying wave processes in three-dimensional elastic cylindrical cavities under the influence of stationary loads.

In the article is given information about the integral concept and the history of its origin. In addition to the Riemann integral, which is covered in the school program, a number of other integrals (Riemann-Stiltes, Daniell, Alfred Haar, Henstock-Kurzweil, Ito and Stratonovich, Chokvet) are described. The difference between integrals is explained with the help of specific examples. The concept of definite integral and its use in practical problems were explained in detail, counter-examples of some theorems were presented.
