On a conjecture of Atiyah
R. I. Grigorchuk, P. Linnell, T. Schick +1
In this note we explain how the computation of the spectrum of the lamplighter group from \cite{Grigorchuk-Zuk(2000)} yields a counterexample to a strong version of the Atiyah conj…

Integrality of L2-Betti numbers
Thomas Schick
The Atiyah conjecture predicts that the L2-Betti numbers of a finite CW-complex with torsion-free fundamental group are integers. We show that the Atiyah conjecture holds (with an…
