Wall's finiteness obstruction

Erik Kjær Pedersen

The purpose of this note is to give a self contained description of Walls finiteness obstruction.

More examples of discrete co-compact group actions

Ian Hambleton, Erik K. Pedersen

We survey some results and questions about free actions of infinite groups on products of spheres and euclidean spaces, and give some new co-compact examples.

Mean curvature flow as a tool to study topology of 4-manifolds

Tobias Holck Colding, William P. Minicozzi, Erik Kjaer Pedersen

In this paper we will discuss how one may be able to use mean curvature flow to tackle some of the central problems in topology in 4-dimensions. We will be concerned with smooth cl…

Assembly Maps for Group Extensions in -Theory and -Theory with Twisted Coefficients

Ian Hambleton, Erik K. Pedersen, David Rosenthal

In this paper we show that the Farrell-Jones isomorphism conjectures are inherited in group extensions for assembly maps in algebraic -theory and -theory with twisted coeffic…

Stability in controlled L-theory

Erik K. Pedersen, Masayuki Yamasaki

We prove a squeezing/stability theorem for delta-epsilon controlled L-groups when the control map is a fibration on a finite polyhedron. A relation with boundedly-controlled L-grou…

A finite loop space not rationally equivalent to a compact Lie group

Kasper K. S. Andersen, Tilman Bauer, Jesper Grodal +1

We construct a connected finite loop space of rank 66 and dimension 1254 whose rational cohomology is not isomorphic as a graded vector space to the rational cohomology of any comp…
