L^2-Torsion and Bounded Measure Equivalence of Groups
Christian Wegner
This paper has been withdrawn by the author due to an error in the proof of Proposition 4.8.
On the behaviour of the Atiyah Conjecture under taking subgroups and under taking quotients with finite kernel
Christian Wegner
We state and prove a condition under which the strong Atiyah Conjecture carries over to subgroups. Moreover, we show that if a group satisfies the (strong) Atiyah Conjecture then a…
On the classification of fake lens spaces
Tibor Macko, Christian Wegner
In the first part of the paper we present a classification of fake lens spaces of dimension >= 5 whose fundamental group is the cyclic group of order N >= 2. The classification use…
L^2-Invariants of Finite Aspherical CW-Complexes
Christian Wegner
Let be a finite aspherical CW-complex whose fundamental group possesses a subnormal series with a non-trivial elementary amenable g…
On fake lens spaces with the fundamental group of order a power of 2
Tibor Macko, Christian Wegner
We present a classification of fake lens spaces of dimension greater or equal to 5 which have as fundamental group the cyclic group of order N = 2^K, in that we extend the results…
