Stope functions
This appears to be the same thing as the stope functions (or simply stopes) introduced by Kenneth E. Iverson (named by analogy with stope). See his books Math for the Layman (1999) and p58 of Concrete Math Companion (2002). Both precede the paper cited on this page. Qwfp (talk) 11:42, 20 June 2010 (UTC)
