An amenable, radical Banach algebra [PDF]

arXiv, 2002
We give an example of an amenable, radical Banach algebra, relying on results from non-abelian harmonic analysis due to H. Leptin, D. Poguntke and J. Boidol.

The moduli space of 6-dimensional 2-step nilpotent Lie algebras [PDF]

arXiv, 2003
We determine the moduli space of metric 2-step nilpotent Lie algebras of dimension up to 6. This space is homeomorphic to a cone over a 4-dimensional contractible simplicial complex.

2-step nilpotent Lie groups arising from semisimple modules [PDF]

arXiv, 2008
Every finite dimensional real representation of a compact real semisimple Lie algebra determines a metric 2-step nilpotent Lie algebra and a corresponding simply connected metric 2-step nilpotent Lie group N. We study the differential geometry of N using representation theory of the complexified complex semisimple Lie algebra.

Totally Geodesic Subalgebras of Filiform Nilpotent Lie algebras [PDF]

arXiv, 2011
