Singularity Theory and Geometry

January to June 1997

In 1997 The Fields Institute will sponsor a program in Singularity Theory and Geometry. All activities will take place during the period January to June 1997 at The Fields Institute in Toronto. The program will include workshops and graduate courses and several lecture series and seminars. The participation of graduate students and postdoctoral fellows will be an integral part of the program's activities. (All activities of The Fields Institute are subject to availability of funds.)

Organizing Committee

Edward Bierstone (University of Toronto), Askold Khovanskii (University of Toronto), Pierre Milman (University of Toronto), Alex Nabutovsky (University of Toronto), Mark Spivakovsky (University of Toronto)
