Small TYPES workshop Curry-Howard Implementation Techniques/Connecting Humans and Type-checkers 2006 The CHIT Workshop discuss implementation issues.Keywords: * Terms and binders * Type inference, type constraints and unification * Reduction, evaluation and compilation * Proof refinement/Proof engine * State handling, library, modules, saving format * Coercions * Termination checking The CHAT workshop will focus on interaction between users and proof environments, graphical interfaces, and on network-based interaction. Keywords: * Declarative versus procedural proof styles (structured proofs, XML) * Web based interfaces (including cooperative environments) * Libraries and information retrieval (including search engines) * Proof documentation (literate proving) * Protocols for UI-interaction
