The next meeting of the Joint Seminar of Analysis, Geometry and Topology Department will be held on June 9, 2015 (instead of June 2, as earlier announced) at 14:00 in Room 478 of IMI.

A talk on:

Generalized Pade approximants and extremal distribution of points

will be delivered by Nikolay Ikonomov.

Everybody is invited.

Abstract. Given a regular plane condenser (E, F), let α and β be triangular point tables; α in E, β in F. Let a function f be analytic on E. We prove that, if a sequence of generalized Padé approximants, associated with the point tables α and β, converge maximally to f, then the points (α, β) are extremally distributed with respect to the condenser (E, F).
