Solvability of a nonlocal problem for a hyperbolic equation with integral conditions
Electronic Journal of Differential Equations, 2017 We study a nonlocal problem with integral conditions for a hyperbolic equation two independent variables. By introducing additional functional parameters, we investigated the solvability and construction of approximate solutions.

Вестник Самарского университета: Естественнонаучная серияBoundary 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 StatisticsWe 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.

Studying a system of non-local condition hyperbolic equations
Қарағанды университетінің хабаршысы. Математика сериясыLocal boundary value problems for hyperbolic differential equations have been studied in considerable detail. However, the mathematical modeling of a number of real-world processes leads to nonlocal boundary value problems involving nonlinear hyperbolic

On the $C^∞$-well-posedness of Goursat Problems
Publications of the Research Institute for Mathematical Sciences, 1985 Many authors have investigated about null-solutions of characteristic Cauchy problems. When the coefficients are real-analytic, many systematic results have been obtained. When the coefficients are only C°°, however, few results are known. In this paper, as one of the cases when we can get well-parametrized null-solutions , we consider Goursat problems
