Course detail

Advanced Methods in Mathematical Analysis

FSI-SDR-AAcad. year: 2025/2026

The course is devoted to two basic areas, which partially overlap. The first part is an introduction to the so-called modern theory of (partial) differential equations and related concepts such as generalized functions, Sobolev spaces, embedding theorems, weak and variational formulation of problems. The second part is devoted to selected methods of nonlinear analysis. These are mainly topological methods, monotonicity methods and variational methods. Applications of these methods to different types of problems are also discussed. Elements of differential calculus in normed linear spaces are mentioned.

Department

Institute of Mathematics (ÚM)

Entry knowledge

Differential calculus, integral calculus, linear algebra, ordinary and partial differential equations, functional analysis.

Rules for evaluation and completion of the course

Course-unit credit is awarded on condition of having attended the seminars actively (the attendance is compulsory) and passed a control test during the semester.
Examination: It has an oral form. Theory as well as examples will be discussed. Students should show they are familiar with basic topics and principles and how they are able to illustrate the theory in particular situations.

Aims

The aim of the course is to provide students with an overview of modern and advanced methods (based mainly on functional analysis) suitable, in particular, for the qualitative analysis of linear as well as nonlinear problems for differential equations. Students will became familiar with the generalized formulations (weak and variational) of the problems.
