This phenomenon is indeed very general and robust,
since related approximation results hold
true for all linear nonlocal operators. In particular, no particular
structure (such as ellipticity, parabolicity or hyperbolicity) is needed
to obtain these density results.
In addition, we show that it is possible to make sense of the fractional
Laplacian also for functions with a polynomial growth at infinity, and that
the density results are stable with respect to this extended notion.
