Abstract:
      In this paper, we introduces the concept of graded direct projective modules, ob-tains a critical theorem of graded direct projective modules and characterize graded(left) hereditary rings, graded(left) semihereditary rings, graded(left) semisimple rings and graded(left) pp-rings via graded direct projective modules,
