Discrete Cocompact subgroups of G₅3 and related C*-algebras

الأصل · EN

The discrete cocompact subgroups of the 5-dimensional Lie group G₅3 are determined up to isomorphism. Each of their group C*-algebras is studied by determining all of its simple infinite dimensional quotient C*-algebras. The K-groups and trace invariants of the latter are also obtained.
