Fat realization and Segal's classifying space

Yi-Sheng Wang

In this paper, we give a new proof of a well-known theorem due to tom Dieck that the fat realization and Segal's classifying space of an internal category in the category of topolo…

An approximation of the e-invariant in the stable homotopy category

Yi-Sheng Wang

In their construction of the topological index for flat vector bundles, Atiyah, Patodi and Singer associate to each flat vector bundle a particular C/Z-K-theory class.…

Topological K-theory with coefficients and the e-invariant

Yi-Sheng Wang

We compare the invariants of flat vector bundles defined by Atiyah et al. and Jones et al. and prove that, up to weak homotopy, they induce the same map, denoted by e, from the $…

Simplicial Waldhausen categories and topological K-theory

Yi-Sheng Wang

Utilizing simplicial Waldhausen theory, we prove that the geometric realization of the topologized category of bounded chain complexes over complex numbers (resp. real numbers) is…
