Complex analytic spaces and coherent sheaves
Several complex variables from the Cauchy formula to Oka's and Cartan's coherence theorems, the local parametrization theorem and Nullstellensatz, complex spaces, the Dolbeault complex, Hörmander's L2 estimates, Cartan's Theorems A and B on Stein manifolds, and the Cartan-Serre finiteness theorem on compact complex spaces.
Twelve lessons with proofs, examples and exercises. Self-checked by the writing AI, Claude Opus 5.5 (Anthropic).
