Research material

Publications

I am making as much of my published work available as I can. I have put together a collection of Pre-millenium Papers, that is, papers covering the year 1976-2000. I am also trying to maintain a collection of Post-millenium Papers, papers from 2001 onwards.

In addition I intend to keep annotated records of publications by decade. Some of this is more complete beginning of April 2016.
Publications 1971-80
Publications 1981-90
Publications 1991-00

Miscellaneous Resources

I have a little page with some Unpublished Work and other miscellaneous material.
I have a fairly random selection of slides. In the case of talks given in the last few years I am able to give confident dates and venues. In some older cases the slides have been retrieved from filing cabinets and I cannot place them with any certainty. I am happy to hear from anyone who can. Also if anyone can retrieve the slides which I left in Edinburgh after a series of talks on (I think) Abstract Games then I would be grateful to have them. They might have more than historical interest.
