How Does a Non-Atomic Measure Relate to Lebesgue Measure Through a Function?

Click For Summary
SUMMARY

The discussion focuses on the relationship between non-atomic measures and Lebesgue measures through a specific function. It establishes that for a non-atomic measure m defined on the Borel sigma-algebra B(I) of a closed interval I in R, the equality m(S) = L(f(S)) holds, where L represents the Lebesgue measure and f(x) = m(I ∩ (-∞, x]). This relationship is crucial for understanding how non-atomic measures can be represented in terms of Lebesgue measures.

PREREQUISITES

if m(.) is a non-atomic measure on the Borel sigma-algebra B(I).
I is some fixed closed finite interval in R.

How to show that f satisfies the following:

m(S) = L(f(S)), S in B(I) where L is the Lebesgue measure and
f(x) = m( I intersect(-infinity,x] )
