Multicomplexes, bounded cohomology and additivity of simplicial volume
arXiv:math/0109057
Abstract
We discuss some additivity properties of the simplicial volume for manifolds with boundary: we give proofs of additivity for glueing amenable boundary components and of superadditivity for glueing amenable submanifolds of the boundary, and we discuss doubling of 3-manifolds.
