Dear all, We would like to invite you for the 79th meeting of the Peripatetic Seminar on Sheaves and Logic, which will be held in the weekend of the 28th and 29th of June near Utrecht, the Netherlands. It is organized by the University of Utrecht with financial support of the MRI, the Mathematical Research Institute. As a special attraction, Clemens Berger will give a tutorial on theta-categories, a topic from higher-dimensional category theory. For the entire weekend, we will stay at the conference centre "Kaap Doorn", near Utrecht (www.kaapdoorn.nl), which can easily be reached by public transport. Concerning these and other matters a webpage can be consulted, one that is at the moment under construction. The address will be: http://www.math.uu.nl/people/vdberg/PSSL79 Here we will also announce the precise costs for the stay at the conference centre. People who wish to attend the PSSL should send an e-mail to the address below. Please indicate if you want to give a talk. With best regards, The organizers, Jaap van Oosten Federico di Marchi Pieter Hofstra Claire Kouwenhoven-Gentil Benno van den Berg -- Benno van den Berg - Mathematisch Instituut, UU vdberg@math.uu.nl - P.O.box 80.010, 3508 TA Utrecht, NL --
