Title: Indistinguishability, Duality, and Coordination

Abstract: Indistinguishablity is a fundamental notion in distributed systems. It serves as the central tool in impossibility proofs and lower bounds. Indeed, indistinguishability can be used to determine when actions are disallowed. Its dual, which corresponds to the knowledge that a process has, plays the opposite role, and determines when actions are allowed. This talk will discuss the relation between knowledge and action in distributed systems, and present several theorems that apply across all models of distributed computation. The connections drawn also relate a semantic approach, which can be viewed in terms a modal logic, and algorithmic issues.
