On the uniqueness of semi-wavefronts for non-local delayed reaction–diffusion equations
(2015)We establish the uniqueness of semi-wavefront solution for a non-local delayed reaction–diffusion equation. This result is obtained by using a generalization of the Diekmann–Kaper theory for a nonlinear convolution equation. ...
