Coproduct (free product) of two monoids or groups #

In this file we define Monoid.Coprod M N (notation: M ∗ N) to be the coproduct (a.k.a. free product) of two monoids. The same type is used for the coproduct of two monoids and for the coproduct of two groups.

The coproduct M ∗ N has the following universal property: for any monoid P and homomorphisms f : M →* P, g : N →* P, there exists a unique homomorphism fg : M ∗ N →* P such that fg ∘ Monoid.Coprod.inl = f and fg ∘ Monoid.Coprod.inr = g, where Monoid.Coprod.inl : M →* M ∗ N and Monoid.Coprod.inr : N →* M ∗ N are canonical embeddings. This homomorphism fg is given by Monoid.Coprod.lift f g.

We also define some homomorphisms and isomorphisms about M ∗ N, and provide additive versions of all definitions and theorems.

Main results #

The universal property of the coproduct is given by the definition Monoid.Coprod.lift and the lemma Monoid.Coprod.lift_unique.

We also prove a slightly more general extensionality lemma Monoid.Coprod.hom_ext for homomorphisms M ∗ N →* P and prove lots of basic lemmas like Monoid.Coprod.fst_comp_inl.

Implementation details #

The definition of the coproduct of an indexed family of monoids is formalized in Monoid.CoprodI. While mathematically M ∗ N is a particular case of the coproduct of an indexed family of monoids, it is easier to build API from scratch instead of using something like

def Monoid.Coprod M N := Monoid.CoprodI ![M, N]

or

def Monoid.Coprod M N := Monoid.CoprodI (fun b : Bool => cond b M N)

There are several reasons to build an API from scratch.
