DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AthensFAOA/5
 0/">$C^*$-rigidity for certain exponential Lie groups</a>\nby I. Beltita (
 Inst. Math. Romanian Acad.) as part of Functional analysis and operator al
 gebras in Athens\n\n\nAbstract\nA exponential Lie group is called (stably)
  $C^*$-rigid if it is uniquely determined\, within the class of exponentia
 l Lie groups\, by the class of isomorphism (Morita equivalence) of its $C^
 *$ algebra. We discuss the problem of $C^*$-rigidity of exponential Lie gr
 oups. In particular\, we show that generalized $ax+b$-groups are non-rigid
 \, while nilpotent Lie groups of dimension less than equal to 5 are stably
  $C^*$-rigid.\n
