Report

More examples of discrete co-compact group actions

Autor: Hambleton, Ian, Pedersen, Erik K.

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.

Report

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

Autor: Hambleton, Ian, Pedersen, Erik K., Rosenthal, David

Publikováno v: Pure Appl. Math. Q. 8 (2012), no. 1, 175--197

In this paper we show that the Farrell-Jones isomorphism conjectures are inherited in group extensions for assembly maps in algebraic $K$-theory and $L$-theory with twisted coefficients.
Comment: Revisions following a referee's report. Title cha

Stability in controlled L-theory

Autor: Pedersen, Erik K., Yamasaki, Masayuki

Publikováno v: Geom. Topol. Monogr. 9 (2006) 67-86

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-groups is also discussed.
Comment: This is the version published by G

Report

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

Autor: Andersen, Kasper K. S., Bauer, Tilman, Grodal, Jesper, Pedersen, Erik K.

Publikováno v: Invent. Math 157 (2004), no. 1, 1--10.

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 compact Lie group, hence providing a counterexample to a classical conject

Topological Equivalence of Linear Representations for Cyclic Groups, I & II

Autor: Hambleton, Ian, Pedersen, Erik K.

Publikováno v: Ann. of Math. (2) 161 (2005), no. 1, 61--104; Forum Math. 17 (2005), no. 6, 959--1010

In the two parts of this paper we solve a problem of De Rham, proving that Reidemeister torsion invariants determine topological equivalence of linear G-representations, for G a finite cyclic group. Methods in controlled K-theory and surgery theory a
