Webtalking about, you should bet her that one process is adjoint to the other. This almost always works. (d) A given functor G may or may not have a left adjoint, but if it does, it is unique up to isomorphism, so we may speak of ‘the left adjoint ofG’. The same goes for right adjoints. We prove this later (Example 4.3.13). Existence Not every functor G : C → D admits a left adjoint.
