On the Gromov non-hyperbolicity of certain domains in Cn
[Sur la non Gromov hyperbolicité de certains domaines de Cn]
Comptes Rendus. Mathématique, Volume 355 (2017) no. 5, pp. 493-498.

Nous étudions dans cette Note l'hyperbolicité au sens de Gromov de certains domaines de Cn. On démontre que, si Ω est un domaine convexe borné de Cn, n2, et si S est un hyperplan affine complexe tel que ΩS, alors ΩS n'est pas hyperbolique au sens de Gromov. Si X est un domaine convexe de Cn, alors Ω={(z,w)X×C,|w|<eφ(z)} n'est pas Gromov hyperbolique, où φ est une fonction strictement plurisousharmonique sur X et continue sur X.

In this paper, we prove that if Ω is a bounded convex domain in Cn, n2, and S is an affine complex hyperplane such that ΩS is not empty, then ΩS is not Gromov hyperbolic with respect to the Kobayashi distance. Next, we show that if X is a bounded convex domain in Cn, then Ω={(z,w)X×C,|w|<eφ(z)} is not Gromov hyperbolic, where φ is a strictly plurisubaharmonic function on X continuous up to X.
