We give a brief overview of operational models for concurrent systems that exhibit probabilistic behavior, focussing on the interplay between probability and nondeterminism. Our su...
Abstract. Orc is a new language for task orchestration, a form of concurrent programming with applications in workflow, business process management, and web service orchestration. ...
Abstract. We present a capability calculus for checking partial confluence of channel-communicating concurrent processes. Our approach automatically detects more programs to be par...
Abstract. We develop a variant of Gordon and Hankin's concurrent object calculus with support for flexible access control on methods. We investigate safe administration and ac...
Impossible futures equivalence is the semantic equivalence on labelled transition systems that identifies systems iff they have the same "AGEF" properties: temporal logic...
