Let $\mathsf{G}$ be a connected nilpotent Lie group, and let $A$ be a continuous trace subquotient of $C^*(\mathsf{G})$, meaning a subquotient whose spectrum…

Let $G$ be an exponential Lie group and let $C^*(G)$ be its $C^*$-algebra. A continuous-trace subquotient is a quotient $\mathcal J_2/\mathcal J_1$ of $C^*(G)$ by ideals…
