Homological Invariants and Quasi - Isometry
Building upon work of Y. Shalom we give a homological-algebra flavored definition of an induction map in group homology associated to a topological coupling. As an application we obtain that the cohomological dimension cdR over a commutative ring R satisfies the inequality cdR(Λ) ≤ cdR(Γ) if Λ embeds uniformly into Γ and cdR(Λ) < ∞ holds. Another consequence of our results is that the Hirsch ra...
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.

متن کاملHomological Farrell invariants for embedded graphs
A very general recursive graph invariant, introduced by E.J. Farrell, is revisited and extended to graphs embedded into surfaces, by use of the surface homology.
متن کاملSome Homological Conjectures for Quasi-stratified Algebras
In this paper, we are mainly concerned with the Cartan determinant conjecture and the no loop conjecture. If A is an artin algebra of finite global dimension, the first conjecture claims that the Cartan determinant of A is equal to 1, while the second one states that every simple A-module admits only the trivial self-extension. Among numerous partial solutions to these conjectures such as those...
