wow -- great article -- this helped a lot.

Characteristic function

Who says "characteristic function" is "much less frequent now"? It's actually the only term I know for this (I had to guess what an "indicator function" might be, when it showed up in Talk:Boolean algebra). Also the notation I know is χA for the characteristic function of A. --Trovatore 15:26, 6 September 2005 (UTC)[reply]

I agree strongly. I had never hear of "indicator function" before I read the ergodic theory article and linked to this page from there. I propose that this page be renamed to "characteristic function". --Mosher 22:03, 23 September 2005 (UTC)[reply]

You would have to make it a disambiguation page. Characteristic function already refers to the Fourier transform of a distribution of a random variable, which is a standard usage.--CSTAR 22:20, 23 September 2005 (UTC)[reply]
I assume the name indicator function or characteristic function is geographic so I don't think it wise to rule one out or another. As it is called indicator function and not characteristic function where I am.
