REGULAR GLOBAL ATTRACTORS FOR WAVE EQUATIONS WITH DEGENERATE MEMORY [PDF]

open access: yesUral Mathematical Journal, 2019
We consider the wave equation with degenerate viscoelastic dissipation recently examined in Cavalcanti, Fatori, and Ma, Attractors for wave equations with degenerate memory, J. Differential Equations (2016). Under certain extra assumptions (namely on the

Reactive-Diffusive-Advective Traveling Waves in a Family of Degenerate Nonlinear Equations [PDF]

open access: yesThe Scientific World Journal, 2016
This paper deals with the analysis of existence of traveling wave solutions (TWS) for a diffusion-degenerate (at D(0)=0) and advection-degenerate (at h′(0)=0) reaction-diffusion-advection (RDA) equation.

Ergodicity for SDEs and approximations: Locally Lipschitz vector fields and degenerate noise [PDF]

open access: yes, 2002
The ergodic properties of SDEs, and various time discretizations for SDEs, are studied. The ergodicity of SDEs is established by using techniques from the theory of Markov chains on general state spaces, such as that expounded by Meyn-Tweedie ...

Traveling Waves in Degenerate Diffusion Equations

open access: yesCommunications in Mathematical Research, 2023
Summary: In this survey, we present a literature review on the study of traveling waves in degenerate diffusion equations by illustrating the interesting and singular wave behavior caused by degeneracy. The main results on wave existence and stability are presented for the typical degenerate equations, including porous medium equations, flux limited ...

Control and Stabilization of Degenerate Wave Equations [PDF]

open access: yesSIAM Journal on Control and Optimization, 2017
We study a wave equation in one space dimension with a general diffusion coefficient which degenerates on part of the boundary. Degeneracy is measured by a real parameter $μ_a>0$. We establish observability inequalities for weakly (when $μ_a \in [0,1[$) as well as strongly (when $μ_a \in [1,2[$) degenerate equations.

Exact solitary and periodic-wave solutions of the K(2,2) equation (defocusing branch) [PDF]

open access: yes, 2010
An auxiliary elliptic equation method is presented for constructing exact solitary and periodic travelling-wave solutions of the K(2, 2) equation (defocusing branch). Some known results in the literature are recovered more efficiently, and some new exact

The Initial Value Problem for a Degenerate Wave Equation [PDF]

open access: yesProceedings of the American Mathematical Society, 1988
The Cauchy problem for a degenerate wave equation, for which the spatial part is essentially a hypoelliptic sum of squares, is solved via a suitable modification of the standard Hilbert space approach for the usual problem.

Indirect Boundary Controllability of Coupled Degenerate Wave Equations

open access: yesActa Applicandae Mathematicae, 2023
Abstract In this paper, we consider a system of two degenerate wave equations coupled through the velocities, only one of them being controlled. We assume that the coupling parameter is sufficiently small and we focus on null controllability problem.
