Solving the solution of Goursat problem using the Riemann method for a system of fourth order hyperbolic differential equations

Вестник Самарского университета: Естественнонаучная серия
Boundary value problems for certain systems of hyperbolic-type differential equations can be effectively solved using the Riemann method. In this paper, we consider an approach for constructing the Riemann matrix for a system of fourth order hyperbolic ...

Qualitative analysis of fourth-order hyperbolic equations

Frontiers in Applied Mathematics and Statistics
We investigate the qualitative properties of weak solutions to the boundary value problems for fourth-order linear hyperbolic equations with constant coefficients in a plane bounded domain convex with respect to characteristics.

The generalized Goursat-Darboux problem for a third order operator

, 1994
It is proved that if a generalized Goursat-Darboux problem is C#infinity# well posed then the operator cannot contain derivatives with respect to one of the variablesAvailable from Departamento de Matematica, Universidade de Coimbra, 3000 Coimbra ...
