摘要：
In the present work we consider boundary value problems for second order hyperbolic system with higher partial derivatives u(xy), u(xy,) and u(xx,) u(yy). The aim of the study is to find sufficient conditions for solvability of the considered problems by quadratures. We proposed a method for finding explicit solutions for the mentioned problems based on factorization of the equations in the original systems. As a result, in terms of the coefficients of these systems, we obtain 14 conditions for solvability by quadratures for each boundary value problem.
