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 $…
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…
The K-homology of 2-dimensional Crystallographic Groups
Hang Wang, Xiufeng Yao
In this paper we compute the topological K-homology of 2-dimensional crystal groups. Our method focuses on the fixed point of group action and simplifies the calculation of the K-h…
Spectral Asymmetry and Index Theory on Manifolds with Generalised Hyperbolic Cusps
Peter Hochs, Hang Wang
We consider a complete Riemannian manifold, which consists of a compact interior and one or more -cusps: infinitely long ends of a type that includes cylindrical ends and hyperb…
An absolute version of the Gromov-Lawson relative index theorem
Peter Hochs, Hang Wang
A Dirac operator on a complete manifold is Fredholm if it is invertible outside a compact set. Assuming a compact group to act on all relevant structure, and the manifold to have a…
K-homology and K-theory of pure Braid groups
Sara Azzali, Sarah L. Browne, Maria Paula Gomez Aparicio +2
We produce an explicit description of the K-theory and K-homology of the pure braid group on strands. We describe the Baum--Connes correspondence between the generators of the…
