For gasless combustion in a one-dimensional solid, we show a type of nonlinear stability of the physical combustion front: if a perturbation of the front is small in both a spatially uniform norm and an exponentially weighted norm, then the perturbation stays small in the spatially uniform norm and decays in the exponentially weighted norm, provided the linearized operator has no eigenvalues in the right half-plane other than zero. Using the Evans function, we show that the zero eigenvalue must… 
Stability of planar fronts for a class of reaction diffusion systems
The purpose of this thesis is to study stability of one-dimensional traveling waves and multidimensional planar fronts as well as space-independent steady states for a class of reaction diffusion
Stable foliations near a traveling front for reaction diffusion systems
We establish the existence of a stable foliation in the vicinity of a traveling front solution for systems of reaction diffusion equations in one space dimension that arise in the study of chemical
Stability of parabolic-hyperbolic traveling waves
In this paper we investigate nonlinear stability of traveling waves in general parabolic-hyperbolic coupled systems where we allow for a nonstrictly hyperbolic part. We show that the problem is
Pulsating linear in situ combustion: why do we often observe oscillatory behavior?
We have studied simplified, pulsating, one-dimensional, in situ combustion processes. For two cases, with different reaction stoichiometry, oscillations in temperature, flue gas rate, and flue gas
Stability of interacting traveling waves in reaction-convection-diffusion systems
The stability of isolated combustion traveling waves has been exhaustively studied in the literature of reaction-diffusion systems. The analysis has been done mainly by neglecting other waves that
Riemann solutions for counterflow combustion in light porous foam
The paper is motivated by a model for the injection of air into a porous medium that contains a solid fuel. In previous work, a system of three evolutionary partial differential equations that models
Stability of a planar front in a multidimensional reaction-diffusion system
We study the planar front solution for a class of reaction diffusion equations in multidimensional space in the case when the essential spectrum of the linearization in the direction of the front
Stability of Traveling Waves for a Class of Reaction-Diffusion Systems That Arise in Chemical Reaction Models
Perturbations of the wave in $H^1$ or $BUC$ that are small in both the weighted norm and the un Weighted norm are shown to stay small in the unweighted norm and to decay exponentially to a shift of the traveling wave in the weightednorm.
Stability of the steady states in multidimensional reaction diffusion systems arising in combustion theory
. We prove that the steady state of a class of multidimensional reaction-diffusion systems is asymptotically stable at the intersection of unweighted space and exponentially weighted Sobolev spaces,


Combustion Fronts in a Porous Medium with Two Layers
We study a model for the lateral propagation of a combustion front through a porous medium with two parallel layers having different properties. The reaction involves oxygen and a solid fuel. In each
We consider a system of reaction diffusion equations which describe gasless combustion of condensed systems. To analytically describe recent experimental results, we show that a solution exhibiting a
Solitary waves on FPU lattices: II. Linear implies nonlinear stability
In part I of this series (1999 Nonlinearity 12 1601-27), we showed that a two-parameter family of supersonic solitary waves exists in one-dimensional nonintegrable lattices with Hamiltonian H =
Asymptotic stability of solitary waves for the regularized long-wave equation
We show that a family of solitary waves for the regularized long-wave (RLW) equation, is asymptotically stable. The large-time dynamics of a solution near a solitary wave are studied by
Wave sequences for solid fuel adiabatic in-situ combustion in porous media
We study the Riemann problem with forward combustion due to injection of air into a porous medium containing solid fuel. We neglect air compressibility and heat loss to the rock formation. Given

This paper is concerned with the asymptotic stability of travelling wave front solutions with algebraic decay for $n$-degree Fisher-type equations. By detailed spectral analysis, each travelling
