Spring Semester 2009

Functional Analysis

Syllabus

Quick Links:

Summary:
This course covers the basic theorems of functional analysis and provides an introduction to linear operators on Banach spaces. Starting with the abstract notion of topological spaces, we re-develop some of the concepts which were already introduced in Real Analysis in an abstract Banach space setting. The course further contains an introduction to the theory of linear operators, including spectral theory for compact operators, with applications to integral operators and boundary value problems.
