Thanks for the document. I really enjoyed reading it although it's been decades since I actually had to read proper mathematical notations. The author wrote in a concise and clear way that I was able to follow his explanations. I wish he was my professor when I was struggling through college. :)
I actually smiled when he wrote: In general, when an Iverson-bracketed statement is false, we want it to evaluate into a "very strong 0," namely a zero so strong that it annihilates anything it is multiplied by-even if that other factor is undefined. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Andrew Nikitin Sent: Monday, June 28, 2010 12:35 PM To: [email protected] Subject: [Jchat] Knuth on Iverson notation Knuth writes on small portion of Iverson notation (characteristic functions) with examples of its fruitful applications. http://arxiv.org/PS_cache/math/pdf/9205/9205211v1.pdf Not sure if it's been mentioned here _________________________________________________________________ The New Busy think 9 to 5 is a cute idea.
