SUMMARY

The function f(x) = x^{-1}(C_1 + C_2 ln x) is not an element of the L^2(0,1) space for any values of C_1 and C_2 other than both being zero, as the integral diverges at x=0. The discussion emphasizes the relationship between Lebesgue Differentiation and Lebesgue Integration, highlighting that while they are related concepts within measure theory, they serve different purposes. The Lebesgue Differentiation Theorem provides a framework for understanding how functions behave almost everywhere in relation to their integrals.

PREREQUISITES

If some function is element of space ##L^2(0,1)## then
\int^1_0|f(x)|^2dx< \infty. What in the case when it is not so simple to calculate this integral. For example ##f(x)=x^{-1}(C_1+C_2 \ln x)##. How to find is it this function in ##L^2(0,1)## for some ##C_1,C_2##?

It is never (other than both constants = 0). Integral diverges at x=0.
 
Please help me to define Relation between Lebesgue Differentiation and Lebesgue integration?

I have never seen the term Lebesgue differentiation. Lebesgue integration is a theory of integration based on measure theory.
 
Ah, yes, Hawkeye's link is clearly better, more direct than mine.
