Novikov-Shubin invariants for arbitrary group actions and their positivity

چکیده
We extend the notion of Novikov-Shubin invariant for free Γ-CW complexes of finite type to spaces with arbitrary Γ-actions and prove some statements about their positivity. In particular we apply this to classifying spaces of discrete groups.

Power Series over the Group Ring of a Free Group and Applications to Novikov-shubin Invariants
We study power series over the group ring CF of a free group F . We prove that the von Neumann trace maps rational power series over CF to algebraic power series. Using the Riemann-Stieltjes formula, we deduce the rationality and positivity of Novikov-Shubin invariants of matrices over CF .
متن کاملL 2 - Topological Invariants of 3 - manifolds by John Lott and Wolfgang Lück
We give results on the L2-Betti numbers and Novikov-Shubin invariants of compact manifolds, especially 3-manifolds. We first study the Betti numbers and Novikov-Shubin invariants of a chain complex of Hilbert modules over a finite von Neumann algebra. We establish inequalities among the Novikov-Shubin invariants of the terms in a short exact sequence of chain complexes. Our algebraic results, a...
متن کاملNovikov -shubin Signatures, I
Torsion objects of von Neumann categories describe the phenomenon ”spectrum near zero” discovered by S. Novikov and M. Shubin. In this paper we classify Hermitian forms on torsion objects of a finite von Neumann category. We prove that any such Hermitian form can be represented as the discriminant form of a degenerate Hermitian form on a projective module. We also find the relation between the ...
متن کاملHomological Algebra of Novikov-shubin Invariants and Morse Inequalities
It is shown in this paper that the topological phenomenon ”zero in the continuous spectrum”, discovered by S.P.Novikov and M.A.Shubin, can be explained in terms of a homology theory on the category of finite polyhedra with values in certain abelian category. This approach implies homotopy invariance of the Novikov-Shubin invariants. Its main advantage is that it allows to use the standard homol...
متن کاملQuasi-isometry Invariance of Novikov-shubin Invariants for Amenable Groups
We use the notion of uniform measure equivalence to prove that the Novikov-Shubin invariants resp. the capacities of amenable groups are invariant under quasi-isometry. Further, we comment on the connection to Gaboriau’s theorem on the invariance of L-Betti numbers under orbit equivalence.
