Intro
JA: The introduction was specifically written to serve the needs of several disciplines — from math to phil to stat and comp sci — that use concepts related to boolean-valued functions, and to clarify some of the variations in terminology among them. This is the reason for the apparent redundancy of language. Jon Awbrey 05:04, 31 July 2006 (UTC)


 * Certainly all these disciplines make use of indicator functions. But how is "Boolean-valued function" anything other than a synonym for "indicator function"?  One of them should simply be a redirect to the other. --Vaughan Pratt (talk) 05:29, 10 February 2013 (UTC)

Boolean?
This article has the presumption that Boolean-valued mean 0 or 1. Actually, if the range of a function is another Boolean algebra, then the function can be considered Boolean valued. The unnecessary restriction to {0,1} is also perpetuated in Boolean domain, cited from this article.

Furthermore, if {0,1} is to be the range, then propositional function is a more common name for the concept, though indicator function is also used. Perhaps all three articles should be merged. — Rgdboer (talk) 22:54, 3 September 2018 (UTC)
 * Also boolean function seems to be one and the same. Any reason not to merge? Laugh Tough (talk) 18:03, 12 January 2020 (UTC)
