In chapter 2 there are four goals : the first is to investigate some geometric properties of h - caccioppoli sets , the second is to characterize the discontinuous set su and jump set ju of u bvh ( ) , the third is to study pointwise behavior of u bvh ( ) and our effort is concentrated on showing approximate differentiability of u in the sense of pansu ' s , while the last and the most important is to show that dhu with u bvh ( ) as a radon measure can be split into three parts ( absolutely continuous part , jump part and cantor part , respectively ) just like the derivative of a bv function in the setting of euclidean space 第二章有四個目標:一是討論h - caccioppoli集的若干幾何性質,二是刻畫h -有界變差函數的近似不連續點集和跳躍點集的特征,三是研究u bv _ h ( )的逐點行為,我們集中討論u在pansu意義下的近似可微性,最后也是最重要的目標我們證明對u bv _ h ( ) , d _ hu作為radon測度能夠分解成絕對連續部分、跳躍部分和cantor部分之和。
