On the L²-overline{partial}-cohomology of certain complete K\"ahler metrics

Let $V$ be a compact and irreducible complex space of complex dimension $v$ whose regular part is endowed with a complete Hermitian metric $h$. Let $\pi:M\rightarrow V$ be a resolution of $V$. Under suitable assumptions on $h$ we prove that $$H^{v,q}_{2,\overline{\partial}}(\operatorname{reg}(V),g)\cong H^{v,q}_{\overline{\partial}}(M),\ q=0,...,v.$$ Then we show that the previous isomorphism applies to the case of Saper-type K\"ahler metrics and to the case of complete K\"ahler metrics with finite volume and pinched negative sectional curvatures.
