Annotation:
The article is aimed at the study of Clairaut-type differential equations in partial deriva- tives of the first order with a special right-hand side. Finding a general solution for an ordinary Clairaut differential equation is not difficult, and it is described in detail in courses on the theory of ordinary differential equations. In addition to the general solu- tion, which involves a family of integral lines, there is a special solution for an ordinary Clairaut differential equation, represented by the envelope of this family. Within the framework of the theory of differential equations in partial derivatives there are Clair- aut-type differential equations, which are multidimensional generalizations of an ordi- nary Clairaut differential equation. Note that for a Clairaut-type partial differential equa- tion there is no always a special solution. The article is devoted to the problem of the de- scription of a particular solution for Clairaut-type equations, which right side has the form of a power function of the product of n factors.
Keywords:
partial differential equations; Clairaut-type differential equations; singu- lar solutions; power function.
