On the map of Bökstedt-Madsen from the cobordism category to -theory
George Raptis, Wolfgang Steimle
Bökstedt and Madsen defined an infinite loop map from the embedded -dimensional cobordism category of Galatius, Madsen, Tillmann and Weiss to the algebraic -theory of …
Homotopy coherent diagrams and approximate fibrations
Wolfgang Steimle
Let p be a fibration over a finite simplicial complex, whose fibers have the homotopy type of finite simplicial complexes. Then p is equivalent to an approximate fibration whose to…
Obstructions to stably fibering manifolds
Wolfgang Steimle
Is a given map between compact topological manifolds homotopic to the projection map of a fiber bundle? In this paper obstructions to this question are introduced with values in hi…
Higher Whitehead torsion and the geometric assembly map
Wolfgang Steimle
We construct a higher Whitehead torsion map, using algebraic K-theory of spaces, and show that it satisfies the usual properties of the classical Whitehead torsion. This is used to…
