Module aim (aims)
The main goal of Formal Analysis is to investigate formal power series and formal Laurent
series as well. Various applications of that series ranging from algebra to classical
analysis. In particular, it is worth to mention here that it has some applications to
the investigation of the boundary convergence behavior of power series.
The main goal of this course is to introduce basic notions and tools using in
Formal Analysis as well as some of its applications.
A particular emphasis will be put on some new achievements of that theory.
Pre-requisites in terms of knowledge, skills and social competences (where relevant)
One has to have basic knowledge in mathematical analysis. Moreover, some knowledge of basic definitions and facts of functional analysis and metric topology would be also useful.
