View on Github →feat(CategoryTheory): reflecting the property of being precoherent and preregular (#11502)
We prove that given a fully faitful functor F : C ⥤ D
which preserves and reflects finite
effective epimorphic families, such that for every object X
of D
there exists an object W
of
C
with an effective epi π : F.obj W ⟶ X
, the category C
is Precoherent
whenever D
is.
We prove the corresponding result for Preregular
, but then it is enought that F
preserves and reflects effective epis.
