Context setting

 * A closed category can be defined as a category V with an internal homomorphism functor $$V^{op} \times V \to V$$, left Yoneda natural arrows $$L: \left[B\ C\right] \to \left[\left[A\ B\right] \left[A\ C\right]\right]$$ and a fixed object I of V such that there is a natural isomorphism $$i_A: A \to \left[I\ A\right]$$ and a natural transformation $$j_A: I \to \left[A\ A\right].\, $$

Hello. Please note that in the above, there is no way for the typical reader, not being a mathematician, to tell that this article is about mathematics rather than theology, chemistry, diplomatic protocol, etc. I've added "In mathematics," at the beginning. Michael Hardy 20:56, 20 Feb 2005 (UTC)
