Learning objectives

The object of the course is to familiarize the students with the basic language and of some fundamental theorems in General Topology and in the theory of holomorphic finctions of one complex variable.
In particular,
1) the notions of topological spaces, subspaces, product and quotient topology, compact, connected and path-connected spaces, metric spaces and topological groups di spazio metrico will be provided;
2) the basic properties and facts of holomorphic finctions of one complex variable, as Cauchy-Riemann equations, Cauchy Theorem and Cauchy Formula, analytic continuation, Laurent series and residue theorem will be discussed.


Geometry 1, Analysis 1, Algebra.

Teaching methods

Lectures and classroom exercises.
During lectures in traditional mode, the
topics will be formally and rigorously presented. The course will give particular emphasis to application and computation aspects, while not letting out
the theoretical aspect. The classroom exercises are aimed at showing how and where the abstract results can be applied to make the students understand better the relevance of what they are studying.

During the lectures the basic results of calculus for functions of one variable will be analyzed and discussed.Students will be provided also with the basic results on sequences of real numbers and numerical series. The classroom exercises are aimed at showing how and where the abstract results can be applied to make the students understand better the relevance of what they are studying.

Assessment methods and criteria

The exam consists of a written part and an oral part in different dates.
