Introduction to Observational Type Theory
Manage episode 357099588 series 2823367
In this episode, I introduce an important paper by Pujet and Tabareau, titled "Observational Equality: Now for Good", that develops earlier work of McBride, Swierstra, and Altenkirch (which I will cover in a later episode) on a new approach to making a type theory extensional. The idea is to have equality types reduce, within the theory, to statements of extensional equality for the type of the values being equated.
