"Recent results on the

extension problem"

By

Alexander Goncharov

(Bilkent University)

Abstract: Recently  L.Frerick, E. Jorda, and J. Wengenroth
presented a tame extension operator for the space of Whitney
functions on a compact set K,  provided K satisfies a local form of
Markov's inequality. In particular they posed the problem to find a compact set
K satisfying the local form of Markov's inequality with a given parameter, but
not satisfying the global version of Markov's inequality with the same
parameter. We review the suggested construction and discuss the posed problem.

Tea and cookies will be served before the
seminar.
