%T Controlling reversibility in higher-order pi %P 297-311 %I Springer %O 22nd International Conference, CONCUR 2011, Aachen, Germany, September 6-9, 2011. Proceedings Pages %X We present in this paper a fine-grained rollback primitive for the higher-order ?-calculus (HO?), that builds on the reversibility apparatus of reversible HO? [9]. The definition of a proper semantics for such a primitive is a surprisingly delicate matter because of the potential interferences between concurrent rollbacks. We define in this paper a high-level operational semantics which we prove sound and complete with respect to reversible HO? backward reduction. We also define a lower-level distributed semantics, which is closer to an actual implementation of the rollback primitive, and we prove it to be fully abstract with respect to the high-level semantics. %D 2011 %L eprints2489 %S Lecture Notes in Computer Science %A Ivan Lanese %A Claudio Antares Mezzina %A Alan Schmitt %A Jean-Bernard Stefani %N 6901 %R 10.1007/978-3-642-23217-6_20 %B CONCUR 2011 ?
