Mathematical models of analysis of systems of different physical nature

The paper analyzes the properties of various processes, phenomena and objects in which you can make sure that some of them show certain similarities or similarities. Such similarities can manifest themselves both in the structure and in the dynamics of the behavior of objects. In these cases, to construct mathematical models of the behavior of systems of various physical natures, one can use similar equations. Thus, an important basis for modeling the behavior of complex systems uses analogies in changing the behavior of a wide class of systems.
