Professor John McKay of Concordia University Montreal,
will speak on "Computation of Galois Groups"
TIME: 3:30 p.m.
ROOM: MC 1304
ABSTRACT
I shall discuss the developments of the past decade in
automating the computation of Galois groups from
polynomials determining splitting fields. The first
and (to date) only implementation is Ron Sommeling's
code on maple. If time permits, I shall sketch
developments in solving the inverse problem: Which
groups are realisable as Galois groups? The computer
has played a critical role in this work.wlrush@water.waterloo.edu (Wenchantress Wench Wendall) (06/15/89)

Dr. Manuel Bronstein, IBM Thomas-Watson Research Center, Yorkton Heights, N.Y. will speak on "An Overview of Symbolic Integration"
TIME: 3:30 p.m.
ROOM: DC 1304
ABSTRACT
We describe the main lines of decision procedures that
determine whether an elementary function has an
elementary antiderivative. In particular, we show the
links between the residues of a complex algebraic
function and its integrability.
