PROGRAMME COMMITTEE o Ahmed Bouajjani (Paris, France) o Vasco Brattka (Cape Town, South Africa) o Valentin Goranko (Johannesburg, South Africa) o Ker-I Ko (Stony Brook NY, United States of America) o Orna Kupferman (Jerusalem, Israel) o Benedikt Loewe (Amsterdam, The Netherlands) -Chair- o Elvira Mayordomo (Zaragoza, Spain) o Dieter Spreen (Siegen, Germany) o Wolfgang Thomas (Aachen, Germany) o Yde Venema (Amsterdam, The Netherlands) o Klaus Weihrauch (Hagen, Germany) o Philip Welch (Bristol, United Kingdom) o Mariko Yasugi (Kyoto, Japan) o Jeffery Zucker (Hamilton, Canada) OBJECTIVE The conference on Infinity in Logic & Computation is the first conference in South Africa that focuses on infinity in automata theory, logic, computability and verification. One purpose of this conference is to catalyse new interactions among local and international researchers and to expose postgraduate students to recent research trends in these fields. The conference will be organised at the University of Cape Town co-located with the 50th Annual Congress of the South African Mathematical Society (SAMS) that takes place from 31 October until 2 November 2007. We plan to organise a summer school on Logic & Computation directly following the conference from 6-9 November 2007. This summer school is intended for postgraduate students and other interested participants. ORGANISERS o Margaret Archibald (Cape Town, South Africa) o Vasco Brattka (Cape Town, South Africa) o Valentin Goranko (Johannesburg, South Africa) o Hans-Peter Kuenzi (Cape Town, South Africa) o Benedikt Loewe (Amsterdam, The Netherlands) PROCEEDINGS We plan to publish fully refereed post-conference proceedings in the book series of the Association of Logic, Language and Information (FoLLI) that is a sub series of the Lecture Notes in Artificial Intelligence (LNAI) of Springer.
