Integral filling volume, complexity and integral simplicial volume of 3-dimensional mapping tori

Federica Bertolotti, Roberto Frigerio

We show that the integral filling volume of a Dehn twist $f$ on a closed oriented surface vanishes, i.e. that the integral simplicial volume of the mapping torus with monodromy $f^…

Homotopy Equivalences of 3-Manifolds

Federica Bertolotti

Let $M$ be an oriented closed $3$ -manifold. We prove that there exists a constant $A_{M}$ , depending only on the manifold $M$ , such that for every self-homotopy equivalence $f$ of $M…

Length functions on mapping class groups and simplicial volumes of mapping tori

Federica Bertolotti, Roberto Frigerio

Let $M$ be a closed orientable manifold. We introduce two numerical invariants, called filling volumes, on the mapping class group $MCG (M)$ of $M$ , which are defined in te…
