Hi, I would like to buy some booke on category theory and its applications. Can you recommend me the best? Here is what I like: 1. Easy to understatnd, concise book. I like e.g. "Gentle introduction to Haskell" it was quite good with a little of text. There are bigger tutorials in number of pages but there is much less in them. I downloaded "Categories for Software Engineering". I read 2 first chapters, but there is a lot of text and sometimes I need to look on internet to seach for exact definitions/equations which I can understand better. That's why I don't like books "for Dummies" - lot of text, little of content, very shallow and lot of slang. I like "The Haskell: School of expression" and I am searching for another book to read after I finish this. The style of SOE is suitable for me. It is very clear with good theory and examples. But now I want book mainly about theory and the examples as second. 2. With applications and its examples. I would like to see some examples. I doesn't matter if it will be only in pseudo-language in Haskell or another language. What do you think about "Categories and Computer Science (Cambridge Computer Science Texts)" at http://www.amazon.com/Categories-Computer-Science-Cambridge-Texts/dp/0521422... ?
