  • 12.01.18   The proof of claim (ii) in the proof of Perry's estimate (Theorem 3.18) has been made more transparent in the script and its adaptation to the situation in Remark 3.19 is worked out in more details there.
  • 17.10.17   Prerequisites on measures and integration, Banach and Hilbert spaces and bounded operators are summarised in this handout.

Synopsis
The course introduces the basic elements of mathematical quantum mechanics and the necessary analytical tools. Topics to be covered include: observables as self-adjoint operators, spectral theorem for self-adjoint operators, relation between spectral types and dynamics, elements of scattering theory, many-particle systems.

Prerequisites
Basics of functional analysis and quantum mechanics are helpful.

Audience
Master students.
