Category Theory by Tom LaGatta

Tom LaGatta presents a basic introduction to category theory, namely, some of the basic definitions and concepts.  More importantly, emphasizing the role of abstract, categorical thinking in both research and application. Just about anything you care about can be faithfully represented using categories-- even the concept of "representation" itself.  Understand how to use categories in your own work, no background is necessary for the talk, questions and comments throughout are welcome.

Tom LaGattaLa has a PhD in Mathematics from the University of Arizona, and until recently was a postdoc at the Courant Institute at NYU. Tom is currently transitioning to a career in the tech sector.

    Just recently, I bought the following textbook on category theory: Category Theory (Oxford Logic Guides) by Steve Awodey. Also, the book "Algebra" by Thomas Hungerford has a good section on category theory.

      Dear Jenny, I could not find anything in the computer science, math, and philosophy departments. Sincerely, Mike Morelli

    There is a professor in the philosophy department , Hans Halvorson, who teaches category theory. His website, http://www.princeton.edu/~hhalvors/teaching/phi324_s2014, has the midterm and homework problems.

    Tom LaGatta did an excellent job of presenting category theory. He also gave some interesting possible applications of category theory to computer languages and also to business. The audience asked some good questions.

    Really good talk. It went a long way in demystifying and giving perspective to a subject that, albeit worthwhile, suffers from a certain amount of unwarranted hype.

    Really good. He sprinkled in the right degree of entertainment in the information-rich and educational talk. The pace was just right.

    Very good. I learned Category Theory almost 17 years ago from book Robert Goldblatt "Topoi:the categorical analysis of logic". It contains almost everything: basic category theory, Yoneda Lemma, Intuitionistic logic and Heyting algebra and many interesting examples. Maybe someone will find this book useful also.
