On deficiency gradient of groups
Deficiency gradient is a higher dimensional analog of rank gradient. In this paper, we give a combinatorial proof that the fundamental group of a simply connected complex of amenable groups has deficiency gradient zero. We apply this to establish the vanishing of deficiency gradient in special linea...
