Abstract:
In this note, we study the evolution equation
which was introduced by Munoz-Garcia [9]
in the context of erosion by ion beam sputtering.
We obtain an analytic solution that has the similarity form,
which is used in obtaining the coarsening behavior.
This solution has amplitude and wavelength that increase
like
and
,
respectively.
