DESCRIPTION:Cartan subalgebras and C*-diagonals in C*-algebras (motivated 
 by Cartans in von Neumann algebras) build a bridge between C*-algebras and
  topological dynamics\, which led to striking results regarding the existe
 nce of Cartans/C*-diagonals in classifiable C*-algebras. In particular\, t
 his connection was used to construct examples of C*-diagonals in the Jiang
 -Su algebra Z. In this talk\, I will give the idea of how to construct a n
 ew\, tractable C*-diagonal in Z using solely C*-algebraic techniques. This
  is based on joint work with Wilhelm Winter.
