The Centre for Mathematical Social Science at The University of Auckland (New Zealand) has organized a series of lectures and seminars  given by visitors
and members of the Centre in the period of 13–22 of December 2010. This page remains as an archive.

Talks were accompanied by discussions of future research directions and research collaborations in small groups with participation of visitors and local researchers including PhD and graduate students. Links on talks go to slides provided by the speakers. All information below is from the earlier announcements and has not been updated.
