### Secondary Novikov-Shubin invariants of groups and quasi-isometry

Shin-ichi OGUNI

#### Abstract

We define new $L^{2}$-invariants which we call secondary Novikov-Shubin invariants.We calculate the first secondary Novikov-Shubin invariants of finitely generated groups by using random walk on Cayley graphs and see in particular that these are invariant under quasi-isometry.
