Query: Studying the topological stability of the $\lambda\Phi^4 $ kink   The lambda-phi4 kink is linearly and topologically stable. We study how extra
energy perturbations are dissipated beyond the linear regime. We found that
depending on the width, amplitude and energy of a Gaussian perturbation
different scenarios are possible: radiation, oscillons creation, kink anti-kink
pairs production and shock waves.
