Résumé
Abstract

Motivés par une question de J. Globevnik, nous montrons qu'une immersion holomorphe propre du disque unité $D$ dans $C^{2}$ ou un plongement holomorphe propre $f : D \to C^{3}$ peut avoir une croissance arbitraire. En outre, en utilisant les séries entières tropicales, nous caractérisons les poids radiaux w sur le plan complexe pour lesquels il existe $n \in N$ et une application holomorphe propre $f : C \to C^{n}$ tels que $| f (z) |$ soit équivalente à $w (z)$ .

Motivated by a question of J. Globevnik, we show that a proper holomorphic immersion of the unit disk $D$ into $C^{2}$ or a proper holomorphic embedding $f : D \to C^{3}$ may have arbitrary growth. Also, using tropical power series, we characterize those radial weights w on the complex plane for which there exist $n \in N$ and a proper holomorphic map $f : C \to C^{n}$ such that $| f (z) |$ is equivalent to $w (z)$ .
