Dispersive and dissipative properties of the fully discrete bicompact schemes of the fourth order of spatial approximation for hyperbolic equations

Applied Numerical Mathematics, 2019
The Fourier analysis of fully discrete bicompact fourth-order spatial approximation schemes for hyperbolic equations is presented. This analysis is carried out on the example of a model linear advection equation.

Stochastic non-isotropic degenerate parabolic–hyperbolic equations [PDF]

, 2016
We introduce the notion of pathwise entropy solutions for a class of degenerate parabolic–hyperbolic equations with non-isotropic nonlinearity and fluxes with rough time dependence and prove their well-posedness.

New Generalized Hyperbolic Functions to Find New Exact Solutions of the Nonlinear Partial Differential Equations

Journal of Mathematics, 2013
We firstly give some new functions called generalized hyperbolic functions. By the using of the generalized hyperbolic functions, new kinds of transformations are defined to discover the exact approximate solutions of nonlinear partial differential ...

Hyperbolic differential-operator equations on a whole axis

Abstract and Applied Analysis, 2004
We give an abstract interpretation of initial boundary value problems for hyperbolic equations such that a part of initial boundary value conditions contains also a differentiation on the time t of the same order as equations.

Hyperbolic Stefan problem with nonlocal boundary conditions

Математичні Студії
In this paper, we consider problems with unknown boundaries for hyperbolic equations and systems with free boundaries with two independent variables. The boundary conditions for such equations in the linear or quasilinear cases are given in nonlocal (non-

Nonoscillatory Central Schemes for Hyperbolic Systems of Conservation Laws in Three-Space Dimensions

The Scientific World Journal, 2013
We extend a family of high-resolution, semidiscrete central schemes for hyperbolic systems of conservation laws to three-space dimensions. Details of the schemes, their implementation, and properties are presented together with results from several ...
