Variation motivation of the equation of deformation of the general stiltyesovsky string
In the article, the equation modeling deformations of "the general stiltyesovsky string" is being studied. In the mathematical literature this equation is based usually on sending to engineering mathematics or purely speculative generalizations of a usual string. For the correct analysis where it is necessary to consider non-classical indignations, we will count necessary to give exact variation motivation of this equation (item 2.1.). This equation is related to the ordinary differential equation. The corresponding properties are established in item 2.2.
