Dependent Types

  • Feb 10, 2014 · 7:00 PM
  • Mixrank

Our tour of the lambda calculi is approaching its high point, the dependently typed lambda calculus. After telling us how to use lambda calculus to make terms from terms and terms from types, Tikhon will show us how to make types from terms, thereby greatly simplifying some things while complicating others.

Also, it looks as if we have quora for exploring at least a couple of different topics:

. Dependent types and theorem proving through Coq and/or Idris

. Coding of lambda calculus interpreters

. And perhaps logic programming

Yet to be decided is just how to organize the subgroups on these topics, and when and where to meet. Tikhon has set up a new Google group for us to discuss these topics (and others) at!forum/sf-ttpl, because many people find the interface inconvenient for discussions.

Remember: *1111 opens the gate at Mixrank!

    This cast some clarity on dependent types, which are a complex subject.

    I finally put the slides for dependent types and System F (from last time) up on Yay.

    Sorry, I've been sick and couldn't attend. Hope to see the talk online in some form!

    So what is the front door protocol? Last time I got quite desperate and was about to give up and leave, but just at that point someone let me in.

      Type *1111 on the keypad at the door.

      I ended up leaving last time...although to be perfectly honest, I might have gotten the date wrong. =(
