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.
