We show that typability for a natural form of polymorphic recursive typing for rank-2 intersection types is undecidable. Our proof involves characterizing typability as a context ...
Peers in peer-to-peer file-sharing systems use conjunctive queries as a way of controlling query cost in the absence of information about the behavior of other peers. Conjunctive ...
We study the implication that various timeliness and failure detector assumptions have on the performance of consensus algorithms that exploit them. We present a general framework...
Typical interaction models as addressed messages present several pitfalls. To overcome these limits, new interactional models close to the concept of mutual awareness have been pro...
Presently, there is no satisfactory model for dealing with political autonomy of agents in policy based management. A theory of atomic policy units called ‘promises’ is therefo...
