International audience; Given a pair (G,a) where G is a finitely presentable group and a is an integer homology class of this group, Gromov defined in his article "Filling Riemannian manifolds" a new numerical invariant associated to this pair called

Let G be a finitely presentable group and fix a nontrivial homology class a2Hm.G;Z/ of dimension m 1. In order to study topological and algebraic properties of the class a , we consider the various ways this class can be realized by a pseudomanifold
