Computational
Analysis Seminar. Maxym Yattselev, INRIA Sophia Antipolis. Non-Hermitian Orthogonal Polynomials with Varying Weights on an Arc. We consider multipoint Pade approximation of Cauchy transforms
of complex measures. We show that if the support of a measure is a smooth
Jordan arc and the density of this measure is sufficiently smooth, then
the diagonal multipoint Pade approximants associated with interpolation
schemes that satisfy special symmetry property with respect to this arc
converge locally uniformly to the approximated Cauchy transform. The
existence of such interpolation schemes is proved for the case where
support is an analytic Jordan arc. The asymptotic behavior of Pade
approximants is deduced from the analysis of underlying non-Hermitian
orthogonal polynomials.

In the online version of this page, all underlined
phrases are links; some mathematical symbols may require a browser with symbol font. Past
calendars are available, as well as
next week's calendar (in preparation)
and a web page listing
just our colloquia.
We update the online calendar whenever we get information,
but generally we only print paper copies on Fridays.
Please submit events as early as possible, to math.calendar@vanderbilt.edu.
