A geometric Elliott invariant and noncommutative rigidity of mapping tori
Hao Guo, Valerio Proietti, Hang Wang
We prove a rigidity property for mapping tori associated to minimal topological dynamical systems using tools from noncommutative geometry. More precisely, we show that under mild…

Persistence approximation property for operator algebras
Hang Wang, Yanru Wang, Jianguo Zhang +1
In this paper, we study the persistence approximation property for quantitative -theory of filtered operator algebras. Moreover, we define quantitative assembly maps for $…

Equivariant Spectral Flow and Equivariant -invariants on Manifolds With Boundary
Johnny Lim, Hang Wang
In this article, we study several closely related invariants associated to Dirac operators on odd-dimensional manifolds with boundary with an action of the compact group of iso…
