Abstract:
This article provides a regularity criterion for the surface quasi-geostrophic
equation with supercritical dissipation. This criterion is in terms of the
norm of the solution in a Orlicz-Morrey space.
The result shows that, if a weak solutions
satisfies
for some
and
,
then
is regular at t=T. In view of the embedding
with
and P>1, our result extends the results
due to Xiang [29] and Jia-Dong [15].
