Full abstraction, totality and PCF

1999 Mathematical Structures in Computer Science  
Inspired by a question of Riecke, we consider the interaction of totality and full abstraction, asking whether full abstraction holds for Scott's model of cpos and continuous functions if one restricts  ...  Analysing further, we consider sequential and parallel versions of PCF and several models: Scott's model of continuous functions, Milner's fully abstract model of PCF and their effective submodels.  ...  Acknowledgments I would like to thank Samson Abramsky for reawakening my interest in totality and domain theory, and Ulrich Berger, John Longley and Dag Normann for interesting and informative discussions  ...

Axioms for Definability and Full Completeness [article]

Samson Abramsky
2014 arXiv   pre-print
Axioms are presented which encapsulate the properties satisfied by categories of games which form the basis of results on full abstraction for PCF and other programming languages, and on full completeness  ...  Axioms are presented on models of PCF from which full abstraction can be proved.  ...  I am grateful to Guy McCusker and the two anonymous referees for their comments on the preliminary version of this paper.  ...

Denotational Semantics with Nominal Scott Domains

Steffen Lösch, Andrew M. Pitts
2014 Journal of the ACM  
For both languages, we prove a full abstraction result for nominal Scott domains analogous to Plotkin's classic result about PCF and conventional Scott domains: two program phrases have the same observable  ...  To obtain full abstraction, we need to add two functionals, one for existential quantification over names and one for "definite description" over names.  ...  THEOREM 8.5 (FULL ABSTRACTION FOR λν-PCF + ).  ...

Full Abstraction and the Context Lemma

Trevor Jim, Albert R. Meyer
1996 SIAM journal on computing (Print)  
It is impossible to add a combinator to PCF to achieve full abstraction for models such a s Berry's stable domains in a way analogous to the addition of the parallel-or" combinator that achieves full abstraction  ...  A simple argument demonstrates that any denotational semantics that is adequate for PCF, and in which certain simple Boolean functionals exist, cannot be fully abstract for any extension of PCF satisfying  ...  As an aside, we also point out that it is questionable whether the bistable and similar domains are closer to full abstraction for PCF.  ...

He proved that this model is computationally adequate for PCF, but not fully abstract. “In order to obtain full abstraction he extended PCF by a parallel conditional operator.  ...  “Here we address the problem of full abstraction for the origi- nal sequential language PCF, i.e. instead of extending the language we try to improve the model.  ...
