Query: Transition fronts for inhomogeneous Fisher-KPP reactions and non-local
  diffusion   We prove existence of and construct transition fronts for a class of
reaction- diffusion equations with spatially inhomogeneous Fisher-KPP type
reactions and non-local diffusion. Our approach is based on finding these
solutions as perturbations of appropriate solutions to the linearization of the
PDE at zero. Our work extends a method introduced by one of us to study such
questions in the case of classical diffusion.
