Online talks The list is incomplete because for many years I rarely allowed my talks to be recorded and posted online. The talks listed here are those I have been able to find online. There are several versions of some talks, slightly different. New talks will be added when available

September 1988, Paris, Stokes phenomenon: smoothing a Victorian discontinuity. Although the first minutes are missing, I include this because it was my first talk on this aspect of asymptotics (it’s listed, incorrectly, as ‘quantum anholonomy) https://www.youtube.com/watch?v=Lu3ifk1RsbU&t=19s
