Extracting Purely Functional Contents from Logical Inductive Types
We propose a method to extract purely functional contents from logical inductive types in the context of the Calculus of Inductive Constructions. This method is based on a mode con...

Automatic Termination Proofs for Programs with Shape-Shifting Heaps
We describe a new program termination analysis designed to handle imperative programs whose termination depends on the mutation rogram's heap. We first describe how an abstrac...
