Hahn is a Coq library that contains a useful collection of lemmas and tactics about lists and binary relations.
- Hahn.v : exports all other files except HahnExtraNotation.v
- HahnAcyclic.v : proving acyclicity of relations
- HahnBase.v : basic tactics used throughout the development
- HahnCountable.v : countable sets
- HahnDom.v : (co)domain of a relation
- HahnEquational.v : relational equivalences
- HahnExtraNotation.v : notation for decidable equality.
- HahnFun.v : functional update
- HahnFuneq.v : functional preservation properties of relations
- HahnLift.v : lifting relations to partial equivalence relations
- HahnList.v : lemmas about lists
- HahnListBefore.v : list-induced ordering
- HahnMaxElt.v : maximal elements of a relation
- HahnMinElt.v : minimum elements of a relation
- HahnNatExtra.v : a few properties of natural numbers
- HahnWf.v : well-founded and finitely supported relations
- HahnMinPath.v : minimal paths/cycles over relations
- HahnOmega.v : natural numbers with infinity
- HahnPath.v : paths over relations
- HahnRelationsBasic.v : binary relations
- HahnRewrite.v : support for rewriting equivalent relations
- HahnSets.v : lemmas about sets (i.e., unary relations)
- HahnSegment.v : lemmas about segments of total orders
- HahnSorted.v : lemmas about sortedness of lists
- HahnTotalExt.v : extension of a partial order to a total order.
- HahnTotalList.v : building finite relations for program order.
- HahnTrace.v : possibly infinite sequences.
- Zorn.v : A mechanization of Zorn's lemma (thanks to Johannes Kloos)
