Generalized Positive Energy Representations of the Group of Compactly Supported Diffeomorphisms

Bas Janssens, Milan Niestijl

Motivated by asymptotic symmetry groups in general relativity, we consider projective unitary representations $ρ$ of the Lie group $Diff_{c} (M)$ of compactly suppor…

Holomorphic Induction Beyond the Norm-Continuous Setting, With Applications to Positive Energy Representations

Milan Niestijl

We extend the theory of holomorphic induction of unitary representations of a possibly infinite-dimensional Lie group $G$ beyond the setting where the representation being induced…

Generalized Positive Energy Representations of Groups of Jets

Milan Niestijl

Let $V$ be a finite-dimensional real vector space and $K$ a compact simple Lie group with Lie algebra $k$ . Consider the Fréchet-Lie group $G := J_{0}^{\infty} (V; K)$ of $\in…
