The aim of this course is an introduction in the theory of holomorphic functions of several complex variables |

Content |

1. Holomorphic functions of several complex variables. General properties. Equivalent definitions, the integral representation formula on polydisc, power series. The identity theorem for holomorphic function, maximum principle, sequences of holomorphic functions. Hartogs' theorem.
2. Holomorphic mappings. General properties. Biholomorphic mappings. The equivalence between univalence and biholomorphy. Cartan uniqueness results. The biholomorphic automorphisms of the unit ball and polydisc. 3. Pluriharmonic and plurisubharmonic functions. Properties. 4. Domains of holomorphy. Properties and examples of domains of holomorphy. Holomorphic convexity. properties. The equivalence of these notions. 5. Pseudoconvex domains. Hartogs pseudoconvexity and Levi pseudoconvexity. General properties. Necessary and sufficient conditions of pseudoconvexity. The equivalence of these notions in the case of domains with differentiable boundary. 7. The equivalence between pseudoconvexity and holomorphic convexity. 8. Subclasses of biholomorphic mappings on the unit ball of C^n: starlike and convex mappings. Growth, covering and distortion results. Examples. |
