OVERVIEW
The theory of operator algebras and operator theory has held a significant
place in the Canadian mathematical community for many years. One of the centrepieces
of the field in Canada has been the Canadian Operator Symposium (COSy). Founded
by Israel Halperin in the early 1970’s, the meeting will be held for
the 41st time in Toronto.
The overall goals of the meeting are:
 to bring in international leaders in the field to explain the most topical
recent developments to the Canadian community,
 to highlight the current research activities of the leaders within Canada
and,
 to provide a resource for young researchers  graduate students, postdoctoral
fellows and young faculty.
