Language: Italian (unless otherwise requested)
This course consists of 60 hours of lectures, including 12 hours of exercises.
The course consists essentially of two parts. The first, whch is the main part, is a standard introduction to complex analysis, from first definitions to the residue theorem. The second part contains a selection of topics, including the theory of Euler's Gamma function.
The couse aims at giving to students the bases of complex analysis. In particular, at the end of the course the students will understand the basic concepts of complex analysis and will be able to use them to solve some problems.
The course consists of traditional lectures and exercises sessions. Moreover, exercises will be given to students for independent training.
Power series: formal power series; convergent power series; analytic functions. Complex differentiation: holomorphic functions; Cauchy-Riemann equations; conformal transformations; elementary functions. Complex integration: integration along paths; primitives; Cauchy's theorem. Consequences of Cauchy's theorem: Cauchy's integral formula; holomorphic functions are analytic; further consequences (theorems by Morera and Liouville, mean value, maximum modulus, Weierstrass' convergence theorems). Singularities and residues: Laurent series; behavior near singularities; residue theorem and applications. Miscellanea: zeros and poles of meromorphic functions; Euler's Gamma function; analytic continuation.
