利用Whitney方体的相关性质,给出了一类调和函数在半空间中无穷远点处的增长估计,且刻画了其例外集的几何性质.本文推广了张艳慧和邓冠铁在半空间中的相关结果.
By using related properties of Whitney cubes, the authors give growth estimates for a class of harmonic functions at infinity in a half space, and characterize geometrical properties of exceptional sets. The related results of Y. H. Zhang and G. T. Deng in a half space are then extended.
