### Connecting degrees of parallelism and Boolean algebras through classical realizability

Denotational models of functionnal programming languages (such as PCF) may contain so-called non-sequential functions : functions which exist in the denotational model but do not correspond to any program. For example, Scott's model of continuous functions has parallel or, while Berry's stable model has Gustave's function. Using constructs which come from Krivine's classical relizability (notably the characteristic Boolean algebra Gimel 2), we show how these non-sequential functions and the question of their relative strength (in terms of their ability to emulate one-another) can be connected to the theory of Boolean algebras.
