Hi,
Thank you for all the replies to my previous questions.
It is very helpful.
Now, I have another (trivial) question.
If I have two constant functors Delta_X and Delta_Y that respectively
returns X and Y in C, then their comma category is the discrete category
C(X,Y).
How do comma categories generalize to bicategories?
When C is a 2-category, I would like the "comma category" of the
"functors"(?) Delta_X and Delta_Y be the (not necessarily discrete) category
C(X,Y).
