C^n
monoid #
A C^n
monoid is a monoid that is also a C^n
manifold, in which multiplication is a C^n
map
of the product manifold G
Γ G
into G
.
In this file we define the basic structures to talk about C^n
monoids: ContMDiffMul
and its
additive counterpart ContMDiffAdd
. These structures are general enough to also talk about C^n
semigroups.
Basic hypothesis to talk about a C^n
(Lie) additive monoid or a C^n
additive
semigroup. A C^n
additive monoid over G
, for example, is obtained by requiring both the
instances AddMonoid G
and ContMDiffAdd I n G
.

, then it is continuous. This is not an instance for technical
reasons, see note [Design choices about smooth algebraic structures].

Left multiplication by g
. It is meant to mimic the usual notation in Lie groups.
Used mostly through the notation π³
.
Lemmas involving smoothLeftMul
with the notation π³
usually use L
instead of π³
in the
names.
