Extensionality of Spatial Observations in Distributed Systems
We discuss the tensions between intensionality and extensionality of spatial observations in distributed systems, showing that there are natural models where extensional observati...

An Extensional Spatial Logic for Mobile Processes
Existing spatial logics for concurrency are intensional, in the sense that they induce an equivalence that coincides with structural congruence. In this work, we study a contextual...

A Bi-Directional Refinement Algorithm for the Calculus of (Co)Inductive Constructions
The paper describes the refinement algorithm for the Calculus of (Co)Inductive Constructions (CIC) implemented in the interactive theorem prover Matita. The refinement algorithm ...

Extensional Equality in Intensional Type Theory
We present a new approach to introducing an extensional propositional equality in Intensional Type Theory. Our construction is based on the observation that there is a sound, inte...
