Measuring E and f in Product Space of Borel Measures

Click For Summary
SUMMARY

The discussion focuses on the measurability of sets and functions within the context of Borel measures in R^2. It establishes that if E is a Borel measurable subset of R, then the set {(x,y) | x-y is in E} is also measurable in the product space of Borel measures. Additionally, it confirms that if f is a measurable function, then the function F(x,y) = f(x-y) is also measurable. These conclusions are critical for understanding the properties of measurable sets and functions in higher dimensions.

Show that if E is a Borel measurable subset of R, then {(x,y)| x-y is in E} is also measurable in the product space of Borel measures...

Also, if f is a measurable function, show that F(x,y)=f(x-y) is also measurable..

You must show you work before we can help you.

In the meantime: What do you know about measurable sets in R^2 ?
