Objectives of studying the discipline

mastering the language of modern mathematics by students, mastering general constructs and the ability to apply them in theoretical and applied problems.

  As a result of studying the academic discipline, the student should be able to:

– Identify the design of functional analysis in specific problems;

– set properties of mappings in function spaces;

– apply the results of functional analysis to solve theoretical and applied problems;



Algebra and number theory,

Discrete Math,

Analytic geometry,

Mathematical analysis,

Differential equations,

Theory of functions of a complex variable

Teaching Methods

interactive methods of teaching (working in small groups (team), problem training) are organized taking into account the inclusion in the learning process of all students of the group. Joint activity means that each student makes his own individual contribution, in the course of the work there is an exchange of knowledge, ideas, methods of activity. Organized individual, steam and group work. Interactive methods are based on the principles of interaction, activity of trainees, reliance on group experience, mandatory feedback





Conditions (requirements), current control

– test;

– colloquium

The score on the exam is set taking into account: 30% – work in laboratory and practical classes, 70% – oral examination.
