We describe formalization of the Poincaré disc model of hyperbolic geometry within the Isabelle/HOL proof assistant. The model is defined within the complex projective line ℂP1 and is shown to satisfy Tarski's axioms except for Euclid's axiom — it is shown to satisfy it's negation, and, moreover, to satisfy the existence of limiting parallels axiom.
It has been accepted for publication in the Electronic Proceedings in Theoretical Computer Science (EPTCS) volume dedicated to the ADG 2023 proceedings.
We define and implement CV2EC, a translation from CryptoVerif assumptions on primitives to EasyCrypt games. CryptoVerif and EasyCrypt are two proof tools for mechanizing game-based proofs. While CryptoVerif is primarily suited for verifying security protocols, EasyCrypt has the expressive power for verifying cryptographic primitives and...
