Categories For Types by Roy Crole
Having read the Pierce book on category theory, I really wanted to see how category theory could be used for giving a denotational semantics to functional programming languages. This book was a great explanation of how that can be done. It contains introductory chapters on domain theory and category theory and then dives into categorical semantics, including the relationship between Cartesian Closed Categories and the lambda calculus. Some of the details were too much for me, but I do feel that reading the book has given me a good understanding of this branch of computer science. Over the next few weeks, I will be spending time working through the examples.
