Lambda Calculus by Dustin Mulcahey

A Friendly Introduction to the Lambda Calculus

LISP has its syntactic roots in a formal system called the lambda calculus. After a brief discussion of formal systems and logic in general, I will dive in to the lambda calculus and make enough constructions to convince you that it really is capable of expressing anything that is "computable". Time permitting, I will talk about the simply typed lambda calculus and the Curry-Howard-Lambek correspondence, which asserts that programs and mathematical proofs are "the same thing".

Dr. Dustin Mulcahey holds a PhD in Mathematics with a specialization in Homotopy Theory.

    Good talk. Dustin's humor and personality add a lot. He's now on my list of speakers to follow.

    Dustin did an awesome job of presenting Lambda Calculus and given us a really good sense of what computing in this formal system is like. However Dustin needs to learn the importance of wff's and balanced parentheses. :-)

    Congratulations on taking a potentially dry topic which could have put the audience to sleep but instead making a fun, lively presentation. The high point must have been the spontaneous applause when you showed that 2+2=4 using Church numerals.

    A casual overview, or an in-depth talk?

    • Pierre de L.

      I suspect a little more on the in-depth side. :-)
