Ëì - Calculus and Böhm ’ S Theorem

The-calculus is an extension of the-calculus that has been introduced by M Parigot to give an algorithmic content to classical proofs. We show that B ¨ ohm's theorem fails in this calculus. §1. Introduction. The-calculus (its typed and untyped versions) has been introduced by M. Parigot in [6]. Its typed version is an extension of the typed-calculus intended to give an algorithmic content to cl...

Regular Böhm trees

Böhm trees are the natural infinite generalisations of normal forms in pure λ-calculus. They arose from the work of Böhm on separability (Böhm 1968), and were first identified by Barendregt, who devotes chapter 10 of his book (Barendregt 1980) to their study, and relates denotational models such as D∞ to appropriate quotients over Böhm trees. There is however no generally agreed presentation of...

A 1994 University of Chicago study entitled The Social Organization of Sexuality found that on average men have 74% more opposite­gender partners than women, confirming a view that men are more promiscuous. But whoever reported this finding was lying or confused! We’ll show you how to use the properties of vertex degrees in a graph to prove this. Let’s recast opposite­gender partnering in graph...
