On propagation failure in 1 and 2 dimensional excitable media
Georg A. Gottwald, Lorenz Kramer
We present a non-perturbative technique to study pulse dynamics in excitable media. The method is used to study propagation failure in one-dimensional and two-dimensional excitable…

A robust numerical method to study oscillatory instability of gap solitary waves
Gianne Derks, Georg A. Gottwald
The spectral problem associated with the linearization about solitary waves of spinor systems or optical coupled mode equations supporting gap solitons is formulated in terms of th…
