View on Github →feat(Algebra/Category/Grp/LargeColimits): large colimits in the category of commutative additive groups (#20522)
If F : J ⥤ AddCommGrp.{w}
is a functor, we show that F
admits a colimit if and only
if Colimits.Quot F
(the quotient of the direct sum of the commutative groups F.obj j
by the relations given by the morphisms in the diagram) is w
-small.
