Hi, this might sound like a stupid question (and most likely it is). What do we know about representing homologies between singular chains via cobordisms? let me be more specific, given a smooth closed n-dim manifold $M$, and two homologous chains $\alpha$ and $\alpha'$ of degree $n-1$ which can be both represented by two codim 1 sub manifolds $V,V'$.
