Jaap van Oosten \documentstyle[12pt,a4]{article} \pagestyle{empty} \nofiles \begin{document} \begin{center} {\Large\bf Announcement 56$^{\mbox{\small\bf th}}$ PSSL} \end{center} The 56$^{\mbox{\scriptsize th}}$ {\em Peripatetic Seminar on Sheaves and Logic} will be held in the weekend of 3 and 4 December at the University of Aarhus, Denmark. As usual, we welcome talks on topics in logic, category theory and related areas in mathematics and computer science. Please publicize this meeting amongst your colleagues. At the time of the meeting, Ieke Moerdijk is in Aarhus as a guest of the Mathematics Department. The meeting will be jointly sponsored by the Mathematics department and the research centre BRICS (Basic Research In Computer Science), so no fees are to be expected. There are two airports serving Aarhus: Tirstrup (Aarhus airport), which is about 50 kilometres from the city and has a good bus connection to it, and Billund, which lies about 100 kilometres from Aarhus and has connection by bus (directly) or bus to Vejle and train from there (in some instances, the latter connection is quicker). Further details, also about accomodation, will follow. As we try to arrange relatively cheap accomodation in student houses, it will be appreciated if attendants register as soon as possible. \medskip Return, preferably by email, to \begin{tabbing} aaaaaa\=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\=\kill \> Jaap van Oosten, \> Tel.~++45-8942 3468\\ \> Datalogisk Afdeling, \> Fax ++45 8942 3255\\ \> Aarhus Universitet \> Email {\tt jvoosten@daimi.aau.dk} \\ \> Ny Munkegade, Bld.~540 \\ \> DK-8000 Aarhus C, Denmark \end{tabbing} We look forward to seeing you in Aarhus.\\ The local organizers, \begin{quote} \begin{tabbing} Anders Kock\qquad\qquad\qquad \= Sergei Soloviev \qquad\qquad \= Vladimiro Sassone\\ Claudio Hermida\> Jaap van Oosten \end{tabbing} \end{quote} \hrule\vskip3pt I would like to attend the 56th PSSL:\\ \\ Name\dotfill \\ Return Address\dotfill \\ \hbox{}\dotfill\\ email \dotfill \\ $\Box$ I wish to give a talk entitled \dotfill\\ of 20/30/45 minutes.\\ I wish to book accomodation from\dotfill to \dotfill \\ \end{document}
