PSSL 87 in Patras - Honouring A. Kock, on the occasion of his 70th birthday The 87th Peripatetic Seminar on Sheaves and Logic will be held in Patras, Greece, the weekend 22-23 March 2008. The meeting will have an extra festive character, honouring Anders Kock on the occasion of his 70th birthday. For that reason an extra session of invited talks will take place on Friday 21 March. A. Joyal, F.W. Lawvere and G. Reyes have accepted to participate in the celebration with plenary talks. People who wish to attend may thus plan for a longer stay than a usual PSSL would imply. The need for a longer stay is propped by the fact that Patras is, for most people in the community, a more remote destination than those in central and western Europe where Peripatetic Seminars were previously held. Please take also into account that the weekend 22-23 March is that of the Catholic Easter (not of the Greek Orthodox one though). Travelling information, possible arrangements for transportation from Athens airport and further details will appear in the webpage www.math.upatras.gr/~pssl87 People who wish to attend may fill out the following registration form and submit it to pssl87@math.upatras.gr ======================== REGISTRATION FORM Name: .......
