调和函数的Lipschitz型空间和Landau-Bloch型定理

Lipschitz Type Spaces and Landau-Bloch Type Theorems for Harmonic Functions

主要研究调和函数和Poisson方程的解的性质.讨论了调和函数的Lipschitz型空间,建立了调和函数的Schwarz-Pick型引理,并利用所得结果证明了与调和Hardy空间有关的一个Landau-Bloch型定理.最后,还利用正规族理论讨论了与Poisson方程的解有关的Landau-Bloch型定理的存在性.

We investigate some properties on harmonic functions and solutions to Poisson equations. We will discuss the Lipschitz type spaces on harmonic functions. Secondly, we establish the Schwarz-Pick type lemma for harmonic functions in the unit ball B^n of R^n, and then we apply it to obtain a Landau-Bloch type theorem for harmonic functions in Hardy spaces. At last, we use a normal family argument to extend the Landau-Bloch type theorem to functions which are solutions to Poisson equations.
