The variant of the Goursat problem for the sixth order equation [PDF]

open access: yes, 2006
Our study is considered as a continuation of results in [1-8]. More precisely we investigate the Goursat problem in class C2+2+2(D) for the equation (1) below by Riemann method variant from the works [8] and [9]

Well-posedness of the Goursat problem and stability for point source inverse backscattering

open access: yes, 2017
We show logarithmic stability for the point source inverse backscattering problem under the assumption of angularly controlled potentials. Radial symmetry implies Hölder stability.

Goursat problem for the Yang-Mills-Vlasov system in temporal gauge

open access: yesElectronic Journal of Differential Equations, 2011
This article studies the characteristic Cauchy problem for the Yang-Mills-Vlasov (YMV) system in temporal gauge, where the initial data are specified on two intersecting smooth characteristic hypersurfaces of Minkowski spacetime $(mathbb{R}^{4},eta )$

Solvability of a nonlocal problem for a hyperbolic equation with integral conditions

open access: yesElectronic 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.

The generalized Goursat-Darboux problem for a third order operator

open access: yes, 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 ...

A fourth-order compact finite difference scheme for the goursat problem

open access: yes, 2013
A high-order uniform Cartesian grid compact finite difference scheme for the Goursat problem is developed. The basic idea of high-order compact schemes is to find the compact approximations to the derivatives terms by differentiating centrally the ...

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

open access: yesВестник 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 ...
