Oct 21, 2019 at 14:33 comment added Dmitri Pavlov Definition 4.6.8 in Riehl's book says: A subobject of an object c ∈ C is a monomorphism c′ ↣ c with codomain c. Isomorphic subobjects, that is, subobjects c′ ↣ c ↢ c′′ with a commuting isomorphism c′ ≅ c′′, are typically identified.

The previous title was ungrammatical. I have edited it with a guess at the intended meaning. If I guessed incorrectly, please correct.

Oct 20, 2019 at 12:53 comment added David White I found it hard to figure out what you were actually answering, so I might recommend highlighting the actual question in the future. By the way, can you say where in Riehl's book she defines a subobject to be any monomorphism?
