Homework 8
Recall that a constant functor between two categories \(\mathbb C\) and
\(\mathbb D\) is a functor sending each object of \(\mathbb C\) to a fixed
object \(A\) in \(\mathbb D\), and each arrow in \(\mathbb C\), to \(1_A\).
Describe all situations when a constant functor is isomorphism of categories.
