Aims	Appropriation of the basic knowledge of the theory of complex functions of a complex variable and the presentation of some applications of this theory.	
Content	1. Analytical  branches.  The index of a path. The homological version of Cauchy's theorem. 
2. Residues. Meromorphic functions. The principle of argument's variation. Rouche's theorem. The open  mapping theorem.
3. The geometric theory of holomorphic functions: Conformal mappings. Conformal automorphisms of the unit disc and  of annuli. Normal families. Montel's and Vitali's theorems. Conformal equivalence of simply connected domains. The Riemann mapping theorem. Continuity at  the boundary.
4. Properties of univalent functions on the unit disc. The class S.   
5. Infinite series and products. The theorems of Weierstrass and Mittag-Leffler.
6. Harmonic and subharmonic functions. Poisson representation of harmonic functions.
