Interchanging a limit and an integral: necessary and sufficient conditions

Abstract Let { f n } n ∈ N $\{f_{n}\}_{n \in \mathbb {N}}$ be a sequence of integrable functions on a σ-finite measure space ( Ω , F , μ ) $(\Omega, \mathscr {F}, \mu )$ . Suppose that the pointwise limit lim n ↑ ∞ f n $\lim_{n \uparrow \infty } f_{n}$ exists μ-a.e. and is integrable. In this settin...
