| 摘 要： | 调和函数在SG3上的Dirichlet边值问题是分形分析领域的重要研究内容之一。考虑通过垂直切割自相似图形SG3，得到SG3上的特定定义域。对于边界值为Cantor集的新的自相似图形，试图探讨在该定义域上的性质。在研究SG3左半定义域上的Dirichlet边值问题的过程中，借助SG3上的二元有理点的调和函数值和正则导数求解格林函数。进一步，运用调和函数的有限能以及弱公式化等方法，最终得到了SG3左半定义域上的格林函数表达式及其相应的定理。

| Abstract: | The Dirichlet boundary value problem for harmonic function on SG3 is one of the important research topics in the field of fractal analysis. In this paper, the specific sub-domain of SG3 generated by vertical cut from self-similar set SG3 is addressed. We study the properties of this new self-similar structure which has the boundary of Cantor sets. To solve the Dirichlet boundary value problem on the left sub-domain of SG3, we introduce the normal derivative and the harmonic function of the dyadic points on SG3. Furthermore, by using the harmonic functions of finite energy and the weak formula, the explicit expression of the Green's function on the left sub-domain of SG3 and its corresponding theorem are obtained. |
