Now I’ve settled in to Italy (and my new job), it’s time to resurrect the blog.

By Karl Crary, from ICFP 2010, available from Karl Crary’s website:

We present a technique for higher-order representation of substructural logics such as linear or modal logic. We show that such logics can be encoded in the (ordinary) Logical Framework, without any linear or modal extensions. Using this encoding, metatheoretic proofs about such logics can easily be developed in the Twelf proof assistant.

Associated Twelf code can be found here.
