Question

What conditions are necessary to prove that the upper and lower integrals of a bounded function exist?

Tap to reveal answer

Answer

Using the definition for Riemann sums to define the upper and lower integrals of a function answers the question.

According the the Riemann sum where represents the upper integral and the following are defined:

1. The upper integral of on is

$(U)\int_$a^bf$(x)dx:=$\text{inf}$\begin{Bmatrix} U(f,p)) \end{Bmatrix}$ where is a partition of .

2. The lower integral of on is

$(L)\int_$a^bf$(x)dx:=$\text{sup}$\begin{Bmatrix} L(f,p)) \end{Bmatrix}$ where is a partition of .

3. If 1 and 2 are the same then the integral is said to be

$\int_$a^bf$(x):=(U)\int_$a^bf$(x)dx=(L)\int_$a^bf$(x)dx$

if and only if , $b\ \epsilon\ \mathbb{R}$ , , and $f:[a,b]\rightarrow \mathbb{R}$ be bounded.

Therefore the necessary condition for the proving the upper and lower integrals of a bounded function exists is if and only if , $b\ \epsilon\ \mathbb{R}$ , , and $f:[a,b]\rightarrow \mathbb{R}$ be bounded.
