Gromov's theory of multicomplexes with applications to bounded cohomology and simplicial volume
Roberto Frigerio, Marco Moraschini
The simplicial volume is a homotopy invariant of manifolds introduced by Gromov in 1982. In order to study its main properties, Gromov himself initiated the dual theory of bounded…

Ideal simplicial volume of manifolds with boundary
Roberto Frigerio, Marco Moraschini
We define the ideal simplicial volume for compact manifolds with boundary. Roughly speaking, the ideal simplicial volume of a manifold measures the minimal size of possibly ide…
