(3) Prove that if a sequence (fn)n converges to f in measure, then the limit f
is unique, almost everywhere.
(Hint: first show that for every & > 0,
{\f − g\ > €} = {\ƒ - fn] > } U {19 - fnl > > {})
(4) Prove that if a sequence (fn)n converges to f in measure, then the sequence
(Ifn)n converges to [f] in measure, too.
