Annotation

This work is dedicated to the study of certain properties of the classical solution to a one-dimensional mixed problem for one class of fourth order nonlinear equations. By multiplying the equation under consideration by a suitable function and performing subsequent term by term integration, a theorem on the a priori estimation  of the classical solution to the mixed problem is proven

Keywords

nonlinear equation
classical solution
a priori estimate.
mixed problem
