Educational objectives
Acquisition of the basic knowledge of the theory of functions of a complex variable, aimed at a broader understanding of topics addressed in other courses and, more generally, at a deeper scientific maturity, necessary for approaching advanced texts. In particular, the study of Complex Analysis helps clarify certain aspects of the theory of functions of a real variable, such as the theory of line integrals and the domain of convergence of power series. The objective is to provide additional analytical tools and to develop problem-solving skills, including in applied contexts.
Prerequisites
Knowledge of the classical topics of Mathematical Analysis I and II, in particular the theory of real-valued functions of one and several variables, the theory of line integrals, and linear differential forms.
Teaching methods
The course is delivered through lectures, supported by software such as GeoGebra and NotebookLM. The theoretical material is complemented by exercises aimed at illustrating and further developing the topics covered.
Other information
The course is included in the General track of the Master’s Degree Programme in Mathematics; it is also recommended as an elective course within the Bachelor’s Degree Programme, in order to provide a stronger foundational preparation for students who intend to pursue a Master’s Degree in a track other than the General one.
Learning verification modality
The exam consists of an oral examination lasting approximately 30–45 minutes, accompanied by the solution of a few exercises. The purpose of the examination is to assess the level of understanding of the course topics, the ability to present them clearly and with awareness, and the acquired skills in solving simple exercises.
It is strongly recommended to take the examination after completing Mathematical Analysis II and III.
