Specifying properties of concurrent computations in CLF. CLF (the concurrent logical framework) is a language for specifying and reasoning about concurrent systems. Its most significant feature is the first-class representation of concurrent executions as monadic expressions. We illustrate the representation techniques available within CLF by applying them to an asynchronous pi-calculus with correspondence assertions, including its dynamic semantics, safety criterion, and a type system with latent effects due to Gordon and Jeffrey.
