The C*-algebra of the Boidol group
Ying-Fen Lin, Jean Ludwig
The Boidol group is the smallest non-*-regular exponential Lie group. It is of dimension 4 and its Lie algebra is an extension of the Heisenberg Lie algebra by the reals with the r…
The C*-algebra of the semi-direct product K and A
Hedi Regeiba, Jean Ludwig
Let be the semi-direct product group of a compact group acting on an abelian locally compact group . We describe the -algebra of in terms of…
Beurling-Fourier algebras on Lie groups and their spectra
Mahya Ghandehari, Hun Hee Lee, Jean Ludwig +2
We investigate Beurling-Fourier algebras, a weighted version of Fourier algebras, on various Lie groups focusing on their spectral analysis. We will introduce a refined general def…
Tensor products of NCDL-C*-algebras and the C*-algebra of the Heisenberg motion groups
Hedi Regeibaand, Jean Ludwig
We show that the tensor product over of two -algebras satisfying the \textit{NCDL} conditions has again the same property. We use this result to des…
On the dual topology of the groups U(n)xH_n
Mounir Elloumi, Janne-Kathrin Günther, Jean Ludwig
Let be the semi-direct product of the unitary group acting by automorphisms on the Heisenberg group . According to Lipsman, the unit…
A retract theorem for nilpotent Lie groups
Ying-Fen Lin, Jean Ludwig, Carine Molitor-Braun
Let $G= \exp(\g)$ be a connected, simply connected nilpotent Lie group. We show that for every -invariant smooth sub-manifold of , there exists an open relatively compa…
