在2019年,Grafakos和Stockdale引入了一个平均Hörmander条件,并证明了一个“有限范围”的Calderón-Zygmund定理。与经典定理相比,它需要较弱的假设条件,并暗示了“有限值域”的有界性。然而,在本文中,我们表明,平均Hörmander条件实际上是足够的,以获得有界的alleven在最坏的情况下。我们使用了一个类似于February man(Acta Math 124:9-36,1970)的方法:形成具有有界重叠性质的Calderón-Zygmund分解,并近似坏的部分。在平均Hörmander条件下,给出了卷积型奇异积分算子有界性的一个判别准则.
In 2019, Grafakos and Stockdale introduced anmean Hörmander condition and proved a “limited-range” Calderón–Zygmund theorem. Comparing their theorem with the classical one, it requires weaker assumptions and implies theboundedness for the “limited-range” instead of. However, in this paper, we show that themean Hörmander condition is actually enough to obtain theboundedness for alleven in the worst case. We use a similar method to that used by Fefferman (Acta Math 124:9–36, 1970): form the Calderón–Zygmund decomposition with the bounded overlap property and approximate the bad part. Also we give a criterion of theboundedness for convolution type singular integral operators under themean Hörmander condition.
