I've written the definition; this article needs far more work. -- Mike Hardy

Should we set characteristic function to be primarily the generating function of probability theory (currently the second definition), and make indicator function the "characteristic function" of a set (currently the first definition)? Which usage is the most frequent for the first definition from the article? (I am more familiar with "indicator function".)

I'd like to extend both definitions, but have much more to add to the probability theory version! Can anyone advise on appropriate disambiguation in this case?

It makes sense to use "indicator function" for the indicator function, since that term is unambiguous, while "characteristic function" is not. AxelBoldt 03:45 14 Jun 2003 (UTC)
