@conference {100, title = {Spatial and Epistemic Modalities in Constraint-Based Process Calculi}, booktitle = {Proceedings of CONCUR}, year = {2012}, publisher = {Springer}, organization = {Springer}, address = {Newcastle upon Tyne, UK}, abstract = {{We introduce spatial and epistemic process calculi for reasoning about spatial information and knowledge distributed among the agents of a system. We introduce domain-theoretical structures to represent spatial and epistemic information. We provide operational and denotational techniques for reasoning about the potentially infinite behaviour of spatial and epistemic processes. We also give compact representations of infinite objects that can be used by processes to simulate announcements of common knowledge and global information.}}, keywords = {Cloud Storage, Concurrency, Constraint Programming, Epistemic Logic, Knowledge, Modal logic, Social Networks}, doi = {10.1007/978-3-642-32940-1}, url = {http://hal.archives-ouvertes.fr/hal-00761116}, author = {Knight, Sophia and Catuscia Palamidessi and Panangaden, Prakash and Valencia, Frank, D.} }
