LAST ANNOUNCEMENT
LATE REGISTRATIONS ARE ACCEPTED

The Fourth of the Biennal Summer Conferences on Category Theory and
Computer Science will be held in Paris (France).

The main purpose of these conferences is to link research in category
theory with computer science.  The importance of categories in
understanding basic issues in computer science is now well established.
Other structures in logic, algebra and topology are also seen as
fundamental and the scope of the conference is to cover
applications of these structures as well.
Proceedings are published in the Springer LNCS series.

Samson Abramsky, Pierre-Louis Curien, Peter Dybjer, Giuseppe Longo,
John Mitchell, David Pitt, Andrew Pitts, Axel Poigne', David Rydeheard,
