 Quote by lugita15 Is that the same as Cauchy in the L1 norm?
Yes, I think Friedman's avoiding that term because this is earlier in the book than the definition of the Lp spaces.

Edit: I thought about it some more, and I have to change my answer to "no". These concepts are almost the same, but the L1 norm only applies to bounded real- or complex-valued functions, while these are extended real-valued functions (that are almost everywhere real-valued).
