ON ONE MIXED PROBLEM WITH INVOLUTION

摘要

In this paper, we examine a mixed problem for an equation with an involutive deviation in the argument and periodic boundary conditions. Using the Fourier method, we obtain a classical solution to the problem with minimal requirements for the initial data of the problem. Also, we used some methods of improving the convergence of the series representing a formal solution.
