How about a list?

How about a simple list of the antiderivative conditions? --35.8.231.15 (|talk) 2 May 2007

That would belong in the article on complex antiderivative conditions, wouldn't it?--Cronholm144 06:25, 14 May 2007 (UTC)[reply]

Edit proposal

May I propose the following edit (essentially pedagogical, some students have asked for it, otherwise it should be explictly said that we are identifing each constant function with its value)?

"The derivative of a constant function is the zero function. Therefore, any constant function is an antiderivative of the zero function. If $U$ is a connected set, then the constant functions are the only antiderivatives of the zero function. Otherwise, a function is an antiderivative of the zero function if and only if it is constant on each connected component of $U$ (those constants need not be equal)." — Preceding unsigned comment added by Algebraonly (talk • contribs) 08:17, 4 February 2016 (UTC)[reply]

I made the change. In the future, don't be shy! Your contributions are welcome here! Ozob (talk) 00:07, 20 July 2016 (UTC)[reply]

Nothing. Just pinging the OP @Algebraonly: to make them aware of the Ozob's message above. :) --CiaPan (talk) 08:45, 20 July 2016 (UTC)[reply]

Holomorphic antiderivative

In the definition of f it needn't be holomorphic. However, in the existence article it seems that in the sentence "In fact, holomorphy is characterized by having an antiderivative locally, that is, g is holomorphic if for every z in its domain, there is some neighborhood U of z such that f has an antiderivative on U." this is assumed. Otherwise take an f which is not harmonic, then ${\frac {\mathrm {d} f}{\mathrm {d} z}}$ won't be holomorphic. — Preceding unsigned comment added by 82.23.81.76 (talk) 14:09, 14 October 2020 (UTC)[reply]
