Nonlinear Supersymmetric (Darboux) Covariance of the Ermakov-Milne-Pinney Equation

, 2002
It is shown that the nonlinear Ermakov-Milne-Pinney equation $\rho^{\prime\prime}+v(x)\rho=a/\rho^3$ obeys the property of covariance under a class of transformations of its coefficient function.

Nonlinear stability of high Lewis number combustion fronts

Indiana University Mathematics Journal, 2009
In this paper a mathematical model is considered that describes combustion processes characterized by a very high Lewis number. The model is known to support a wavefront that asymptotically connects the completely burned and the unburned states, and that is unique up to translation.
