Hyperbolicité du complémentaire d’une courbe dans \(\mathbb P^2\): Le cas de deux composantes (Hyperbolicity of the complements of plane algebraic curves: The two component case). (French. Abridged English version) Zbl 1034.32017
Summary: We prove that the complement of a very generic complex curve with two components in \(\mathbb P^2\) of degrees \(d_1 \leqslant d_2\) is hyperbolic in the sense of Kobayashi in the following cases: \(d_1 \geqslant 5\); \(d_1=4\) and \(d_2 \geqslant 7\); \(d_1=d_2=4\); \(d_1=3\) and \(d_2 \geqslant 9\); \(d_1=2\) and \(d_2 \geqslant 12\). We consider logarithmic jets developed by G. Dethloff and S. Lu [Osaka J. Math. 38, 185–237 (2001; Zbl 0982.32022)], who generalized to the logarithmic situation J.-P. Demailly’s jet bundles [Proc. Symp. Pure Math. 62, 285–360 (1997; Zbl 0919.32014)], and used by El Goul to obtain results about the hyperbolicity of the complement of a very generic curve in \(\mathbb P^2\) in the case of a single component.
