Invariant metrics of model domains near pseudoconcave points

Pascal J. Thomas, Nikolai Nikolov

We give precise estimates of some holomorphically invariant infinitesimal metrics near a pseudoconcave points in a wide family of ``model'' domains for that situation in $\mathbb C…

Removable sets for pseudoconvexity for weakly smooth boundaries

Quang Dieu Nguyen, Pascal J. Thomas

We show that for bounded domains in $C^{n}$ with $C^{1, 1}$ smooth boundary, if there is a closed set $F$ of $2 n - 1$ -Lebesgue measure $0$ such that $\partial Î©\setmin…

Quasi Triangle Inequality for the Lempert function

Nikolai Nikolov, Pascal J. Thomas

The (unbounded version of the) Lempert function $l_{D}$ on a domain $D \subset C^{d}$ does not usually satisfy the triangle inequality, but on bounded $C^{2}$ -smooth strictly…

Optimal bounds for the Kobayashi distance near $C^{2}$ -smooth boundary points

Nikolai Nikolov, Pascal J. Thomas

It is shown that the optimal upper and lower bounds for the Kobayashi distance near $C^{2, I^\pm}$ -smooth strongly pseudoconvex boundary points obtained in L. Kosinski, N. Nik…

Visible $C^{2}$ -smooth domains are pseudoconvex

Nikolai Nikolov, Ahmed Yekta Ãkten, Pascal J. Thomas

We show that a domain that satisfies the visibility property with $C^{2}$ -smooth boundary is pseudoconvex.
