Mazel Maya Khaimovna 6 Aims of the study 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: 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 7 Prerequisites Theory of Probability, Mathematical Statistics, Equations of Mathematical Physics, Optimization Methods, Extremal Problems and Calculus of Variations, Numerical Methods 8 Contents of the discipline Topic 1.
