Building continuous webbed models for System F

We present here a large family of concrete models for Girard and Reynolds polymorphism (System F), in a non categorical setting. The family generalizes the construction of the model of Barbanera and Be-rardi [2], hence it contains complete models for F [5] and we conjecture that it contains models which are complete for F. It also contains sim-pler models, the simplest of them, E2; being a second order variant of the Engeler-Plotkin model E. All the models here belong to the continu-ous semantics and have underlying prime algebraic domains, all have the maximum number of polymorphic maps. The class contains models which can be viewed as two intertwined compatible webbed models of untyped -calculus (in the sense of [8]), but it is much larger than this. Finally many of its models might be read as two intertwined strict intersection type systems
