AB - Given a cohomology class $\xi \in H^2(M;Z)$ there is a smooth submanifold $K\subset M$ Poincaré dual to $\xi $. A special class of such embeddings is characterized by topological properties which hold for nonsingular algebraic hypersurfaces in ${\bf C}P_n$. This note summarizes some results on the question: how does the divisibility of $\xi $ restrict the dual submanifolds $K$ in this class ? A formula for signatures associated with a $d$-fold ramified cover of $M$ branched along $K$ is given and a proof is included in case $d=2$.
