Let Γ be the fundamental group of a finite connected graph G. Let M be an abelian group. A distribution on the boundary ∂Δ of the universal covering tree Δ is an M-valued measure defined on clopen sets. If M has no χ (G)-torsion, then the group of Γ-invariant distributions on ∂Δ is isomorphic to H1 (G, M).
