In this work,a nonlocal Fisher KPP reaction-diffusion problem with the reaction powers α.When α ≥ 1 and the initial mass is greater than or equal to one,or if the initial mass is less than one and 1 < α < 1+2/n,the problem has a unique nonnegative classical solution.Moreover,the asymptotic convergence to the solution of the heat equation is proved.Finally,numerical results in the super critical case show that solution exists globally.
