MATH 4810/5810, Hilbert Spaces and the Mathematics of Quantum (Information) Theory, August 2022


Dr. Markus Pflaum

Course Contents:

The course will provide an introduction to the theory of Hilbert spaces and their application in Quantum Mechanics. On the mathematical side, the notions of a hermitian inner product, Hilbert space, bounded linear operator, Hilbert basis and Fourier expansion, selfadjointness and the spectrum of a linear operator will be explained. These concepts will then be applied to describe the axioms of Quantum Mechanics and determine the quantum mechanical spectrum of certain Hamilton operators coming from Quantum Mechanics. One of the major goals of the course is to understand and prove the so-called spectral theorem which is crucial to understand Quantum Mechanics.


Lecture Hours and Venue:

MTWThF 9:00 a.m. - 12:00 p.m., August 1 - 18, 2022, ECCR 118.

Office Hours:

after class and by appointment

Course Project:

Each student had to write a short paper (around 5 pages) on a particular topic from Hilbert Space Theory and Quantum Mechanics Topology and give a 10min presentation on this in class. The papers are due August 18, 2020. A selection of possible topics is provided here, but you can propose your own project theme.


Homework assignments will be given in class and usually will be discussed the next day at the beginning of class. Every student should present some homework problem.

Course Literature:

The course will be based solely on textbooks which are freely available for CU students as eBooks through CU Libraries or as online lecture notes under an appropriate open document license.
