摘要
We show that the universal abelian cover of the complement to a germ of a reducible divisor on a complex space with isolated singularity is -connected provided that the divisor has normal crossings outside of the singularity of . We apply this result to obtain a vanishing property for the cohomology of local systems of rank one and we also study vanishing in the case of local systems of higher rank. This second version contains a corrected proof of Corollary 4.1 from the first version.
