Category Theory, Monads, and Computation
Master level course, 4 ECTS. UR1 / ENS Rennes 2020/21 (sif)
The main objective of this course is to introduce a different, yet very rich and powerful, point of view to several constructs and structures the students have already seen. After presenting the basics of category theory, we will investigate the concept of monads in both its theoretical roots and practical use in programming languages. We hope that this course serves as an invitation for master students to enrich their toolbox with open-mindedness, elegance and curiosity.
Keywords Category Theory, Monads, Semantics, Functional Programming, Computation, λ-calculus
