0 1 $begingroup$ If we consider $F colon mathbb{R} to mathbb{R},$ defined as $$ F(x) = left{begin{array}{cc} 0, & mbox{if } x < 0 \ 3, & mbox{if } 0 le x < 4 \ 8, &mbox{otherwise.} end{array}right., $$ and let $mu_F$ the corresponding Lebesgue-Stieltjes measure. What are the measurable sets in this measure? That is, the sets $E$ satisfying $$ mu_F(A) = mu_F(A cap E) + mu_F(A setminus E) $$ $forall A in mathbb{R}.$ real-analysis measure-theory lebesgue-measure share | cite | improve this question asked Dec 3 '18 at 3:08 674123173797 - 4 674123173797 - 4 145 8 ...
