The Existence of a Unique Solution of the Hyperbolic Functional Differential Equation

open access: yesDemonstratio Mathematica, 2014
We consider the Z. Szmydt problem for the hyperbolic functional differential equation. We prove a theorem on existence of a unique classical solution and the Carathéodory solution of the hyperbolic equation.

Implicit methods for the simple wave equation [PDF]

open access: yes, 1984
A family of finite difference methods is developed for the numerical solution of the simple wave equation. Local truncation errors are cal- culated for each member of the family and each is analyzed for stability.

Cauchy problem for the system of the general hyperbolic differential equations of the forth order with nonmultiple characteristics

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
We consider the Cauchy problem for the hyperbolic differential equation of the forth order with nonmultiple characteristics. We generalize this problem from the similar Cauchy problem for the hyperbolic differential equation of the third order with ...

Uniform stabilization of a coupled structural acoustic system by boundary dissipation

open access: yesAbstract and Applied Analysis, 1998
We consider a coupled PDE system arising in noise reduction problems. In a two dimensional chamber, the acoustic pressure (unwanted noise) is represented by a hyperbolic wave equation.

Spectral problem for the sixth order nonclassical differential equations

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
In this article we investigate the correctness of boundary value problems for a sixth order quasi-hyperbolic equation in the Sobolev space Lu = −D6t u + ∆u − λu (Dt =∂/∂t , ∆ = Σni=1∂2/∂x2i – Laplace operator, λ – real parameter). For the given operator

The exact solutions for the (3+1)-dimensional Boiti-Leon-Manna-Pempinelli equation

open access: yesResults in Physics, 2021
In the paper, we study the Boiti-Leon-Manna-Pempinelli equation with (3 + 1) dimension. By using the modified hyperbolic tangent function method, we obtain more new exact solutions for the (3+1)-dimensional Boiti-Leon-Manna-Pempinelli equation, which ...
