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]
