Welcome

On the weekend of 21 - 22 May 2016, the 100th PSSL (Peripatetic Seminar in Sheaves and Logic) took place at the Centre for Mathematical Sciences in Cambridge.

The start of PSSL

The PSSL was founded 40 years ago by Dana Scott, who attended this 100th PSSL and also gave the Mordell Lecture for the Faculty of Mathematics on the preceding Friday, 20 May.
To remember and celebrate the History of PSSL, we have a list of all previous PSSL meetings, compiled by Peter Johnstone. If you can contribute any of the few missing gaps (mainly some talk titles), we would be very grateful! Please email Peter Johnstone (ptj at dpmms.cam.ac.uk)
