Rank, combinatorial cost and homology torsion growth in higher rank lattices
We investigate the rank gradient and growth of torsion in homology in residually finite groups. As a tool, we introduce a new complexity notion for generating sets, using measured groupoids and combinatorial cost. <br/>As an application we prove the vanishing of the above invariants for Farbe...
