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 the study, the student should be able to: – Identify the design of functional analysis in specific problems; – to set properties of mappings in function spaces; – apply the results of functional analysis to solve theoretical and applied problems |
