                    -  Thursday, July 28, 1988

Professor  Alistair  Watson, Department of Mathematics,
University  of  Dundee, Dundee, Scotland, will speak on
``Best  Approximation  of  Complex-Valued Functions and
Data''.

TIME:                3:30 PM

ROOM:              DC 1302

ABSTRACT

Some   numerical  methods  for  best  approximation  of
complex-valued  data  are  first reviewed, with special
emphasis  on the l  and l   norms. The main part of the
                  1      oo
talk  is  concerned  with the problem of best Chebyshev
approximation  of a given complex function on a contour
of  the  complex plane, and different approaches to the
solution  of  this  problem  are  discussed.  Numerical
results are presented.
