\(L^2\) methods and effective results in algebraic geometry. (Méthodes \(L^2\) et résultats effectifs en géométrie algébrique.) (French) Zbl 0962.14014

Séminaire Bourbaki. Volume 1998/99. Exposés 850-864. Paris: Société Mathématique de France, Astérisque. 266, 59-90, Exp. No. 852 (2000).
The paper is a review of analytic methods (\(L^2\) Hodge theory) used in algebraic geometry for studying adjoint linear systems, vanishing theorem for algebraic vector bundles and invariance of plurigenera of general type families. Among the topics discussed in the paper are singular metrics, applications to Fujita’s conjecture [T. Fujita in: Algebraic Geometry, Proc. Symp., Sendai 1985, Adv. Stud. Pure Math. 10, 167–178 (1987; Zbl 0659.14002)] on global generation of adjoint linear systems, and analytic tools in Siu’s proof [Y.-T. Siu, Invent. Math. 134, No. 3, 661–673 (1998; Zbl 0955.32017)] of invariance of plurigenera for a family of general type.
