Decomposition solution of nonlinear hyperbolic equations

open access: yesMathematical and Computer Modelling, 1990
The application of the decomposition method previously proposed by the author to dissipative wave equations of the form \(u_{tt}- u_{xx}+(\partial /\partial t)(f(u))=g\) is discussed. The initial- boundary value problem \(u_{tt}-u_{xx}+(\partial /\partial t)(u^ 2)=-2 \sin^ 2x\cdot \sin t\cdot \cos t,\) \(u(0,t)=u(\pi,t)=0,\) \(u(x,0)=\sin x,\) \(u_ t(x,

Nonlinear Regularizing Effect for Conservation Laws

open access: yes, 2008
20 pagesInternational audienceCompactness of families of solutions --- or of approximate solutions --- is a feature that distinguishes certain classes of nonlinear hyperbolic equations from the case of linear hyperbolic equations, in space dimension one.

Strict solutions of nonlinear hyperbolic neutral differential equations

open access: yesApplied Mathematics Letters, 1999
By using the theory of integrated semigroups, conditions for existence, uniqueness, and regularity of solutions to the Cauchy problem \(x_0=\varphi\in C_E:=C([-r,0],E) \) for the neutral functional-differential equation \[ [x(t) - Lx_t]' = A_0 x(t) + F(t,x_t),\qquad t\geq 0,\tag \(*\) \] are obtained.

Spatial decay estimates for a class of nonlinear damped hyperbolic equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
This paper is concerned with investigating the spatial decay estimates for a class of nonlinear damped hyperbolic equations. In addition, we compare the solutions of two-dimensional wave equations with different damped coefficients and establish an ...

Some theoretical results for a class of neural mass equations

open access: yes, 2010
We study the neural field equations introduced by Chossat and Faugeras in their article to model the representation and the processing of image edges and textures in the hypercolumns of the cortical area V1.

A scaled characteristics method for the asymptotic solution of weakly nonlinear wave equations

open access: yesElectronic Journal of Differential Equations, 1998
We formulate a multi-scale perturbation technique to asymptotically solve weakly nonlinear hyperbolic equations. The method is based on a set of scaled characteristic coordinates.

Bounder solution on a strip to a system of nonlinear hyperbolic equations with mixed derivatives

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2016
The system of nonlinear hyperbolic equations with mixed derivatives is considered on the strip. Time variable of the unknown function changes on the whole axis, and the spatial variable belongs to a finite interval.
