Monofunctors as reflectors
In a well-powered and co-well-powered complete category K with weak amalgamations, the class M of all reflective subcategories with a monofunctor as reflector forms a complete lattice; the limit-closure of the union of any class of elements of M belongs to M. If K has injective envelopes, then the set-theoretical intersection of any class of elements of M belongs to M.
