Query: An iterative estimation for disturbances of semi-wavefronts to the
  delayed Fisher-KPP equation   We give an iterative method to estimate the disturbance of semi-wavefronts of
the equation: $\dot{u}(t,x) = u''(t,x) +u(t,x)(1-u(t-h,x)),$ $x \in
\mathbb{R},\ t >0;$ where $h>0.$ As a consequence, we show the exponential
stability, with an unbounded weight, of semi-wavefronts with speed
$c>2\sqrt{2}$ and $h>0$. Under the same restriction of $c$ and $h$, the
uniqueness of semi-wavefronts is obtained.
