Abstract

We review and apply Cheeger-Gromov theory on l²-cohomology of infinite coverings of complete manifolds with bounded curvature and finite volume. Applications focus on l²-cohomology of (pullback of) harmonic Higgs bundles on some covering of Zariski open sets of Kähler manifolds. The l²-Dolbeault to DeRham spectral sequence of these Higgs bundles is seen to degenerate at E₂.
