Abstract:
Within the framework of this work, three local boundary value problems for a model
equation of hyperbolic type of the third order are formulated and investigated. The solutions of the
problems posed are written out explicitly. Conditions are found for given functions that ensure the
regularity of solutions to the corresponding problems. The obtained representations of solutions to problems
will find applications in further formulations and studies of boundary value problems for various equations
of mixed and mixed-composite types with a similar model operator in the hyperbolicity domain.
Keywords:equations of hyperbolic type of the third order, characteristics of a third order equation,
characteristic coordinates, local problem, nonlocal problem, general solution of the problem, regular
solution of the problem.
