This paper deals with the Cauchy problem of a nonlocal bistable reaction–diffusion equation with , and . Under appropriate assumptions on , it is proved that for any nonnegative and bounded initial condition, this problem admits a global bounded classical solution for , while for , global bounded classical solution exists for large values. Moreover, for small values and small initial data, the solution is shown to converge to 0 exponentially or locally uniformly as , which is referred as the Allee effect.
