Course Overview

This course can be thought of as a continuation of Higher Analysis MATH3611. Functional analysis a central pillar of modern analysis, and we will cover its foundations.

The main emphasis will be on the study of the properties of bounded linear maps between topological linear spaces of various kinds. This provides the basic tools for the development of such areas as quantum mechanics, harmonic analysis and stochastic calculus. It also has a very close relation to measure and integration theory (MATH5825).

Detailed course schedule

  1. Normed linear spaces, bounded operators, Banach spaces.
  2. Functionals and Hahn-Banach theorems.
  3. The Baire-category theorem, the principle of uniform boundedness, the Banach-Steinhaus theorem, the open mapping theorem and the closed graph theorem.
  4. Hilbert space theory; orthonormality, the Riesz representation theorem, projections, convexity.
  5. Operators on Hilbert spaces, normal and selfadjoint operators, spectrum and resolvent, Spectral mapping theorem.
  6. Compact operators, their spectral data, the spectral theorem.
