I talk about my efforts to formalize lambda-calculus with named variables and explicit alpha-equivalence, as originally proposed by Church.  One reason to do that, besides just a love of being ornery, is to be able to state and prove theorems about a... more

A system of word equations is called quadratic if no variable occurs more than twice in it.  There is an interesting simple algorithm to solve quadratic systems of word equations, which I talk through in this episode.  My source is Chapter 12 of "Alg... more

The problem of word equations is a rather storied one, including frustrated connections to Hilbert's Tenth problem.  Word equations relate expressions consisting of concatenations of variables and constant symbols.  An example is a X = X a, where X i... more

In this episode, I give further arguments in favor of coercive subtyping from a software-engineering perspective.  I also explain the critical concept of coherence.
