ABSTRACT
According to §3.6 a norm || · || on Rn assigns to each ndifferential σ = [S] on K a 1-differential ||<r|| = [||S||] > 0 on K . Its upper integral is a norm ι^(||<τ||) < oo on Dn. All such norms on Dn are equivalent; the convergence σ —* 0 in
1-differentials σ* in (2) for each coordinate i.
