RT Book, Section T1 Non-formal compact manifolds with small Betti numbers. A1 Fernández, M. A1 Muñoz, Vicente A2 Bokan, Neda A2 Djorić, Mirjana A2 Fomenko, Anatoly T. A2 Rakić, Zoran A2 Wegner, Bernd A2 Wess, Julius AB We show that, for any k ¸ 1, there exist non-formal compact orientable (k ¡ 1)-connected n-manifolds with k-th Betti number bk = b ¸ 0 if and only if n ¸ maxf4k ¡ 1; 4k + 3 ¡ 2bg.
