Lectures:

• Lecture Series by Prof. S. Thangavelu: "Bargmann and Fock meet Hardy: An uncertainty principle for operators"

In these lectures, we discuss certain bounded linear operators on Fock/twisted Fock spaces leading to the definition of twisted Heisenberg groups $ H^n_\lambda(\C)$. We construct a certain unitary representation of this group and use an operator analogue of Hardy's theorem proves that this representation is irreducible. --:References:--

° The lectures are held on Tuesdays and Thursdays from 11:15 a.m. to 12:30 p.m. in the seminar room next to Higgs Hall.
