Residual finiteness and Abelian subgroup separability of some high dimensional graph manifolds

Main Article Content

Raeyong Kim


We generalize $3$-manifolds supporting non-positively curved metric to construct manifolds which have the following properties : (1) They are not locally $\mathrm{CAT}(0)$. (2) Their fundamental groups are residually finite. (3) They have subgroup separability for some abelian subgroups.
