内容提示: CHAPTER 1Lebesgue MeasureWe know that the length of an interval is de ned to be the di erence between two endpoints. In this chapter, we would like to extend the idea of “length” to arbitrary (or atleast, as many as possible) subsets of R. To begin with, let’s recall...

Lebesgue measure in r-space is an extension of the notion of volume to a larger class of sets. Thus Lebesgue measure has a different meaning in spaces of different dimension. However, since we shall usually regard the dimension as fixed, there is no need to indicate r explicitly in our ...
In this chapter we construct Lebesgue’s measure on ℝ N , and in the following chapter we will develop his method of integration. To avoid getting lost in the details, it will be important to keep in mind what it is we are...
Hello, friends! Let us define the external measure of the set ##A\subset \mathbb{R}^n## as $$\mu^{\ast}(A):=\inf_{A\subset \bigcup_k P_k}\sum_k...
