You do not explain what f-sub-epsilon is, you write f:C-infinity(Rn) -> R+ while, I believe, you mean that f: Rn -> R+
Please make proper changes, so that the article really explains what the Colombeau algebra is.
Best regards

- I fixed this error (nonsense introduced by an anonymous contributor), and several other wrong statements. It's still not perfect (the following "such that" is not very useful), but it should be clear now (nets are functions of the index epsilon, and for given epsilon one gets a C°° function on R^n)... — MFH:Talk 21:13, 28 February 2008 (UTC)
Definition sources confusion edit
I noticed that the definition given in the Basic idea section coincides with Section 8.5 in Colombeau's Multiplication of distributions, but it has no straightforward relation to Gratus's notes, which is the source cited for it. Perhaps this ought to be corrected/clarified. Thanks. Zatrp (talk) 13:16, 4 August 2023 (UTC)
