View on Github →feat(Algebra/Module): the tautological presentation of a module (#18374)
Any A
-module M
admits a tautological presentation by generators and relation.
There is a generator [m]
for any element m : M
, and there are two types of relations:
[m₁] + [m₂] - [m₁ + m₂] = 0
a • [m] - [a • m] = 0
.
