The numerical solutions are computed using an equivalent integral equation instead of a system of differential equations. This avoids uncertainty about the impact of artificial boundary conditions and discretization in time. Stability results also follow from the integral version. Stable kinks have a monotone leading edge and move with a velocity larger than a critical value which depends on the damping strength.engjournal articlehttps//doi.org/10.1103/PhysRevE.69.046601http://link.aps.org/doi/10.1103/PhysRevE.69.046601open access517.9531.1Semiconductor SuperlatticesHarmonic LiquidDiscretePropagationDynamicsEquilibriumFailureSystemsPulsesFísica-Modelos matemáticosEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
