Resumen
Let k be an algebraically closed field and £N = kQ be a path algebra for a tame quiver Q (of type �ÀAn, �ÀDn, �ÀE6, �ÀE7 or �ÀE8). The GR segments, i.e., the sequences of Gabriel¡VRoiter measures which are closed under direct predecessors and successors, will be studied. An upper bound of the number of the GR-segments will be given.
