synopsis:
"A library of abstract interfaces for mathematical structures in Coq."
description: """
We have been working on a new set of foundational interfaces for formalized constructive mathematics in Coq, heavily based on Coq's new type classes, used in a systematic way in order to achieve:
* elegant and mathematically sound abstract interfaces for algebraic and numeric structures up to and including rationals (with practical use of universal algebra and category theory);
* a very flexible purely predicate-based representation of algebraic structures that makes sharing, multiple inheritance, and derived inheritance, all trivial;
* clean expression terms that neither refer to proofs nor require deeply nested record projections;
* fluent rewriting;
* easy and flexible replacement and specialization of data representations and operations with more efficient versions;
* ordinary mathematical notation and overloaded names not reliant on Coq's notation scopes."""

trueDry install with the current Coq version:
opam install -y --show-action coq-math-classes.dev coq.8.10.0[NOTE] Package coq is already installed (current version is 8.10.0). The following dependencies couldn't be met: - coq-math-classes -> coq >= dev Your request can't be satisfied: - No available version of coq satisfies the constraints No solution found, exiting
Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:
opam remove -y coq; opam install -y --show-action --unlock-base coq-math-classes.devtruetrueNo files were installed.
