Abstract:
We obtain the asymptotic behaviour of solutions of the Cauchy problem
for a fractional non-linear equation. We show that the
remainder term in the asymptotic formula is also the remainder in the far
field, that is, as the spatial and temporal coordinates tend to infinity
simultaneously. We also consider the case in which the Cauchy data are not small.
Keywords:
far-field asymptotic behaviour, non-linear heat equation, critical non-linearity.
