Mathematics or Science? | Dec 28, 2022

As part of the program chair’s report for POPL 1992, Andrew Appel wrote a paper titled “Is POPL Mathematics or Science?” His paper measured how theoretical a conference is using the author ordering of the papers published.

Coinduction allows us to define circular or infinite objects (such as streams, lists that can be infinitely long), and to prove things about them.
