Si une variété $X$ projective lisse admet une application holomorphe non-dégénérée $ℂ\to X$ du plan complexe $ℂ$, alors pour chaque représentation linéaire de dimension finie du groupe fondamental de $X$ l’image de cette représentation est presque abélienne. Cela soutient une conjecture proposée par F. Campana, parue dans ce même journal en 2004.

If a smooth projective variety $X$ admits a non-degenerate holomorphic map $ℂ\to X$ from the complex plane $ℂ$, then for any finite dimensional linear representation of the fundamental group of $X$ the image of this representation is almost abelian. This supports a conjecture proposed by F. Campana, published in this journal in 2004.
