Mixed problem for a third order parabolic-hyperbolic model equation

Қарағанды университетінің хабаршысы. Математика сериясы
In 1978, the journal Differential Equations published an article by A.M. Nakhushev, that presented a method for correctly formulating a boundary value problem for a class of second-order parabolic-hyperbolic equations in an arbitrarily bounded domain ...

Further extension of the improved hyperbolic function method with application to general Sawada–Kotera equation of fifth-order, The 3D potential-YTSF equation and (mKdV) equation.

Tikrit Journal of Pure Science, 2018
In this study, a new improved hyperbolic function method is applied for the first time. The proposed method used to calculate more general exact solutions for the general Sawada–Kotera equation of fifth-order, 3D potential-YTSF equation and modified ...

Comparison of high-order methods on unstructured grids [PDF]

, 2013
A high-order Discontinuous Galerkin (DG) method is formulated and implemented on the Cranfield University’s 3D unstructured Finite Volume Method (FVM) code (UCNS3D), for both linear and non-linear hyperbolic conservation laws and for test-cases which ...

Superstability of Some Pexider-Type Functional Equation

Journal of Inequalities and Applications, 2010
We will investigate the superstability of the sine functional equation from the following Pexider-type functional equation ( ), which can be considered the mixed functional equation of the sine and cosine functions, the mixed functional equation of the

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.
