Rigidity of lattices and syndetic hulls in solvable Lie groups

Oliver Ungermann

First let $G$ be a completely solvable Lie group. We recall the proof of the following result: Any closed subgroup of $G$ possesses a unique syndetic hull in $G$ . As a consequence…

Invariant differential operators and central Fourier multipliers on exponential Lie groups

Oliver Ungermann

Let $G$ be an exponential solvable Lie group. By definition $G$ is $*$ -regular if $k e r_{L^{1} (G)} π$ is dense in $k e r_{C^{*} (G)} π$ for all unitary representations $π$ of $G$ . Boid…

L1-determined ideals in group algebras of exponential Lie groups

Oliver Ungermann

A locally compact group $G$ is said to be $*$ -regular if the natural map $Ψ:\Prim C^\ast(G)\to\Prim_{\ast} L^1(G)$ is a homeomorphism with respect to the Jacobson topologies on…
