Query: On the stability of kink-like and soliton-like solutions to the
  generalized convection-reaction-diffusion equation   Stability of the kink-like and soliton-like travelling wave solutions to the
generalized convection-reaction-diffusion equation is studied by means of the
qualitative methods and numerical simulation.
