Annotation
This work is dedicated to the study of certain properties of the almost everywhere solution to a one-dimensional mixed problem for one class of fourth order nonlinear equations. The almost everywhere solution of mixed problem under consideration is sought in the form of Fourier series. After applying Fourier method, the problem of finding unknown Fourier coefficients of sought almost everywhere solution is reduced to solving some countable system of nonlinear integral equations.
