= Processing of 'Category Theory' =


 * : $\S 1.3$: Definition $1.1$


 * : $\S 1.3$: Definition $1.1$

First page it covers: Definition:Composite Mapping.

A very accessible though rigid introduction to category theory. Much gentler than 'Categories work'.

Errata are available at http://www.andrew.cmu.edu/user/awodey/CT2errata2010.pdf.

Progress thus far
Initial set-up complete. --Lord_Farin 20:10, 7 August 2012 (UTC)

Up to $\S 1.8$. End with Definition:Free Category. Continue with Definition:Small Category. --Lord_Farin 10:28, 17 August 2012 (UTC)

Up to $\S 1.9$. --Lord_Farin 17:57, 17 August 2012 (UTC)

Up to $\S 2$, p.29. End with Inverse Relation Functor is Contravariant Functor. Continue with Definition:Injection. --Lord_Farin 09:20, 18 August 2012 (UTC)

Missing Proofs

 * $\S 1.4.13$ Functor between Monoid Categories
 * Theorem $1.6$ Cayley's Theorem (Category Theory)
 * $\S 1.6.4$ Slice Category of Poset Category
 * Example $1.8$ Category of Pointed Sets as Coslice Category

Skipped thus far (that is, what needs to be done still)

 * $\S 1.4.10$ Category of Proofs (context and reach too vague)
 * $\S 1.4.11$ Category of Programs (idem)
 * Some "forgetful functors" in $\S 1.6$
 * Rest of $\S 1.7$ due to lack of rigour in the graph theory compartment.
 * Further exercises from chapter $1$

Other things

 * Many duality stuff is implicit in Awodey, explicate it.
 * Put mathops on the $/$ of slice and coslice categories as this improves the aesthetics.
