這問題出自一道習題 ( Exercise 9 pp.133 W.Rudin:"Real and complex analysis"3d ed.) Suppose that { Fn(x) } is a sequence of positive continuous functions on I=[0,1] ( Fn≧0 ) , that μ is a positive Borel measure on I, and that ( m : Lebesgue measure on I ) (1) lim Fn(x)→0 a.e.[m] (2) ∫Fn(x)dm = 1 for all n (3) lim∫g Fn(x)dm =∫g dμ for every "continuous function g(x) on I" (All integrals are over I) Does it follow that μ nad m are mutually singular (μ⊥m ) 我有一些例子,是符合上述條件而且 μ nad m are mutually singular (μ⊥m ) 所以我"猜測"應該是μ⊥m. 但是我還沒能證出我要的結果 請各位大大給一些提示,困擾了好久.....介.介 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.217.229.176
