Dr. B.C. Gilligan; Professor, Ph.D. 1972 University of Toronto, M.Sc. 1966 University of Toronto, A.B. 1965 Princeton University


Primary Field of Research: Symmetries in complex analysis:


We are currently working on the following, all of which involve the study of the symmetries of complex manifolds under additional assumptions.


Secondary Field of Research:

Family History of the PEADS; particularly, in England

Some Background:

An interesting site containing a wealth of information, including a lot of history of mathematics, has URL:
This is not required, as part of any course, to be read by the students. But it does illustrate how mathematicians have struggled with various ideas over the centuries
and sometimes it took several years, and the work of several different people, in order to develop most topics which are now a part of what we call modern mathematics.
