Due date: November 24 Problem 1 If the measurable fn↘f≥0 with ∫f1<∞, then ∫fn→∫f. Explain the condition ∫f1<∞. Problem 2 Let f∈L1(\R) and fδ(x)=f(δx). Then ∫fδ=1δ∫f. Problem 3 There exists a positive continuous f∈L1(\R) such that lim sup If f\in L^1(\R) is uniformly continuous, then \lim_{|x|\to\infty}f(x) = 0. Problem 4 If f\in L^1(\R) and F(x) = \int_{-\infty}^x f. Then F is uniformly continuous.
