Dear all, We are happy to announce the 98th Peripatetic Seminar on Sheaves and Logic, which will take place during the weekend of 8-10 January 2016. As usual, we invite talks on every aspect of category theory or its applications in mathematics. We have booked a conference centre in a wooded area near the University of Utrecht, which offers full board and lodging and lecture room facilities. We can use some grant money so that the local expenses for the participants will be kept to a minimum. The web site of the centre is http://www.kaapdoorn.com/ (but precise travel instructions will be given in a further announcement). However, we could only make this arrangement for a maximum of 40 participants. We therefore ask participants to register NO LATER than December 17, by an e-mail sent to Benno van den Berg: bennovdberg@gmail.com. Registration will be dealt with on a first come first serve basis. We look forward to seeing you in the new year! Benno van den Berg Ieke Moerdijk Jaap van Oosten [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
