Rotationally invariant periodic solutions of semilinear wave equations

open access: yesAbstract and Applied Analysis, Volume 3, Issue 1-2, Page 171-180, 1998., 1998
Under suitable conditions we are able to solve the semilinear wave equation in any dimension. We are also able to compute the essential spectrum of the linear wave operator for the rotationally invariant periodic case.

Uniform stabilization of a coupled structural acoustic system by boundary dissipation

open access: yesAbstract and Applied Analysis, Volume 3, Issue 3-4, Page 377-400, 1998., 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. The floor of the chamber is subject to the action of piezo‐ceramic patches (smart materials).

Absence of global solutions to wave equations with structural damping and nonlinear memory

open access: yesDemonstratio Mathematica
We prove the nonexistence of global solutions for the following wave equations with structural damping and nonlinear memory source term utt+(−Δ)α2u+(−Δ)β2ut=∫0t(t−s)δ−1∣u(s)∣pds{u}_{tt}+{\left(-\Delta )}^{\tfrac{\alpha }{2}}u+{\left(-\Delta )}^{\tfrac ...

Spatial estimates for a class of hyperbolic equations with nonlinear dissipative boundary conditions

open access: yesBoundary Value Problems, 2011
This paper is concerned with investigating the spatial behavior of solutions for a class of hyperbolic equations in semi-infinite cylindrical domains, where nonlinear dissipative boundary conditions imposed on the lateral surface of the cylinder.

Rogue peakon, posedness and blow-up phenomenon for an integrable Camassa–Holm type equation

open access: yesAdvances in Nonlinear Analysis
In this paper, we study an integrable Camassa–Holm (CH) type equation with quadratic nonlinearity. The CH type equation is shown integrable through a Lax pair, and particularly the equation is found to possess a new kind of peaked soliton (peakon ...
