### Functional Analysis (MATH-308)

This course extends methods of linear algebra and mathematical analysis to spaces of functions, in which the interaction between algebra and mathematical analysis allows powerful methods to be developed. The course will be mathematically sophisticated and will use ideas both from linear algebra and analysis.

Prerequisite

Complex Analysis (MATH-306)

Learning Outcomes

After taking this course the students should be able to independently prove and thoroughly explain central theorems of functional analysis, should be able to apply Hilbert space theory, Riesz representation theorems and theory of operators in problem solving.
