- 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.
