The Lempert function of the symmetrized polydisc in higher dimensions is not a distance

Nikolai Nikolov; Peter Pflug; Włodzimierz Zwonek

We prove that the Lempert function of the symmetrized polydisc in dimension greater than two is not a distance.

Behavior of the Bergman kernel and metric near convex boundary points

Nikolai Nikolov; Peter Pflug

The boundary behavior of the Bergman metric near a convex boundary point z 0 of a pseudoconvex domain D C C is studied. It turns out that the Bergman metric at points z ∈ D in the direction of a fixed vector X 0 E C n tends to infinity, when z is approaching z 0 , if and only if the boundary of D does not contain any analytic disc through z 0 in the direction of X 0 .
