We consider a scalar reaction-diffusion equation containing a nonlocal term
(an integral convolution in space) of which Fisher's equation is a particu
lar case. We consider travelling wavefront solutions connecting the two uni
form states of the equalion. We show that if the nonlocality is sufficientl
y weak in a certain sense then such travelling fronts exist. We also constr
uct expressions for the front and its evolution from initial data, showing
that the main difference between our front and that of Fisher's equation is
that for sufficiently strong nonlocality our front is non-monotone and has
a very prominent hump.
