WebEgoroffs Theorem Assume E has finite measure. Let {f n} be a sequence of measurable functions on E that converges pointwise on E to the real-valued function f. Then for each ϵ > 0, there is a closed set F contained in E for which {f n} → f uniformly on F and m(E ∼ F) < ϵ. 4 Littlewood [Lit41], page 23.
