August 1996- June 1997

In 1996-97 The Fields Institute for Research in Mathematical Sciences will be sponsoring an emphasis year in Algebraic Model Theory. The program will consist of a mixture of workshops, graduate courses and several lecture series and seminars. The participation of graduate students and postdoctoral fellows will be an integral part of the year's activities.
