Dear Category Theorists, This is a last reminder about PSSL100 which is happening in Cambridge on 21/22 May, celebrating 40 years since the start of this series of conferences. You can see all relevant information on the conference website. https://www.dpmms.cam.ac.uk/~jg352/PSSL100/pssl100.html The deadline to propose a talk has now passed; Peter Johnstone will soon inform speakers about who's talk can be accommodated in the programme. The deadline to sign up to the conference dinner in Newnham College is Monday 9 May. [Sorry for short notice: my first message sent a few days ago did not get through.] We hope to see some more last minute sign-ups for this momentous occasion. If you have any questions, or need help finding accommodation, please do not hesitate to contact me (Julia Goedecke, jg352 at cam.ac.uk). Best wishes, Julia -- Dr Julia Goedecke DPMMS, Centre for Mathematical Sciences University of Cambridge Wilberforce Road CB3 0WB jg352@cam.ac.uk [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
