Formalisation of Differentiable Logics in Coq

This repository contains the formalization of the Logic of Differentiable Logics (LDL) using the Coq proof-assistant and the Mathematical Components library. The LDL language is defined in ldl.v, along with its fuzzy, DL2, STL and Boolean interpretations. The files fuzzy.v, dl2.v, dl2_ereal.v, stl.v and stl_ereal.v contain the relevant theorems that hold for each interpretation: structural properties (idempotence, commutativity and associativity of operators), soundness, and shadow-lifting. The files mathcomp_extra.v and analysis_extra.v contain extra lemmas related to the respective libraries, including L'Hopital and Cauchy MVT in the latter.
