Not so much a presentation as a discussion for those interested, as I am not going to be well prepared.

Earlier in the month I went to Padua to work with Milly Maietti on type theory for arithmetic universes, which are not cartesian closed.

We had some interesting thoughts on categorical interpretations, using categories with families or similar structures.

The pervasive problem is how to make substitution strictly functorial. We were exploring a trick that we think is due to Girard.
