Böhm Trees, Krivine’s Machine and the Taylor ... - ResearchGate

The Böhm trees are obtained by considering the λ⊥-terms where the set of meaningless terms consists of those without head normal form. More explicitly, the Böhm tree BT ( M) of a lambda term M can be computed as follows: [10] BT ( M) is. ⊥ {\displaystyle \bot } , if M has no head normal form. See more In the study of denotational semantics of the lambda calculus, Böhm trees, Lévy-Longo trees, and Berarducci trees are (potentially infinite) tree-like mathematical objects that capture the "meaning" of a term up to some … See more The set of λ-terms with ⊥ (abbreviated λ⊥-terms) is defined coinductively by the grammar The Böhm-like … See more A simple way to read the meaning of a computation is to consider it as a mechanical procedure consisting of a finite number of steps … See more We define a set $${\displaystyle U}$$ of meaningless terms as follows: • Root-activeness: Every root-active term is in $${\displaystyle U}$$. A term $${\displaystyle M}$$ is root-active if for all $${\displaystyle M{\stackrel {*}{\to }}N}$$ there exists a redex See more WebAs these enormous trees die, they may remain standing for decades, providing food and shelter for countless species.

WebWhen I study the Bohm tree defined in The Lambda Calculus: Its Syntax and Semantics, H.P. Barendregt, Elseviser,$\cap\Phi$ or $\cup_i(M_i)$ always occurs. But I'm confused about the union and the intersection operation of Bohm trees. WebA Bohm tree represents the communication between too systems.
