Learning Outcomes

On completion of this module, students should be able to.
1. illustrate the basic theory and applications of operator theory;

2. define basic notions from operator theory and recognize their occurrence and relevance in applied problems;

3. solve specific problems from mathematical physics formulated in operator theoretic terms;

4. Perform algebraic and analytic computations based on operator techniques;


IMAPS wishes to introduce new level 3 modules reflecting research interests and expertise of new staff, thereby rectifying the previous problem of very limited range of modules for final year students. This module introduces the important field of operator theory. It is intended to offer this module in alternate years. Operator theory is only represented in the curriculum through spectral theory at present and we would like to introduce it as an option. It has critical importance to areas such as spectral analysis and quantum theory, both of which are strong research topics in the department. It introduces specific concepts central to open quantum systems, fundamental to understanding current research.

Brief description

Modern quantum theory requires mathematical concepts and techniques going beyond traditional techniques encountered in standard textbooks. A proper understanding of these principals involves operator theoretic concepts, which will be presented in the module. The motivation is a description of open quantum systems.


Operators on Hilbert Spaces
Introduction to Hilbert spaces, definitions of bounded, unitary, projective and
self-adjoint operators. Applications of the spectral theorem and Stone's theorem.

Introduction of the notion of abstract operator algebras.
Applied Operator Theory
Motivating examples of operators from Mathematical Physics. Mathematical formulation of
Quantum Theory for closed dynamical systems.

Open Quantum Systems
Introduction to the quantum theory of measurement. Completely positive mappings.
Instruments and measurements. Lindblad's theory of dynamical semi-groups.
