Hello everybody, please help me soit (X,A,µ) espace mesured and f M+. (mesurable positive) Show that ʃ fdµ<+∞ implies f<+∞µpp X and thanks. Last edited by skipjack; December 1st, 2016 at 10:31 PM.

I don't understand what "f<+∞µpp" means.

I believe what she is asking is to show that $f \text{ integrable on X} \Rightarrow \text{ the set of singularities of f on X has measure 0.}$
