L^2-Invariants of Finite Aspherical CW-Complexesmath.GT

Let $X$ be a finite aspherical CW-complex whose fundamental group $π_1(X)$ possesses a subnormal series $π_1(X) \rhd G_m \rhd ... \rhd G_0$ with a non-trivial elementary amenable group $G_0$ . We investigate the $L^2$ -invariants of the universal covering of such a CW-complex $X$ . We show that the Novikov-Shubin invarian…
