Invariant pluricomplex Green functions

Maciej Klimek (1995)

Banach Center Publications

The purpose of this paper is to present a concise survey of the main properties of biholomorphically invariant pluricomplex Green functions and to describe a number of new examples of such functions. A concept of pluricomplex geodesics is also discussed.

k-convexity in several complex variables

Hidetaka Hamada, Gabriela Kohr (2002)

Annales Polonici Mathematici

We define and investigate the notion of k-convexity in the sense of Mejia-Minda for domains in ℂⁿ and also that of k-convex mappings on the Euclidean unit ball.

Kobayashi-Royden vs. Hahn pseudometric in ℂ²

Witold Jarnicki (2000)

Annales Polonici Mathematici

For a domain D ⊂ ℂ the Kobayashi-Royden ϰ and Hahn h pseudometrics are equal iff D is simply connected. Overholt showed that for D n , n ≥ 3, we have h D ϰ D . Let D₁, D₂ ⊂ ℂ. The aim of this paper is to show that h D × D iff at least one of D₁, D₂ is simply connected or biholomorphic to ℂ 0. In particular, there are domains D ⊂ ℂ² for which h D ϰ D .

Lempert theorem for strongly linearly convex domains

Łukasz Kosiński, Tomasz Warszawski (2013)

Annales Polonici Mathematici

In 1984 L. Lempert showed that the Lempert function and the Carathéodory distance coincide on non-planar bounded strongly linearly convex domains with real-analytic boundaries. Following his paper, we present a slightly modified and more detailed version of the proof. Moreover, the Lempert Theorem is proved for non-planar bounded strongly linearly convex domains.
