摘要：
We address the far field regularity for solutions of the surface quasi-geostrophic equation thetat + u.del theta + A(2 alpha)theta = 0 u = R-inverted perpendicular&theta = (-R2theta,R1theta) in the supercritical range 0 < alpha < 1/2 with alpha sufficiently close to 1/2. We prove that if the datum is sufficiently regular, then the set of space-time singularities is compact in R-2 x R. The proof depends on a new spatial decay result on solutions in the supercritical range.
