In this paper, first we present a characterization of semiconvergence for nonnegative splittings of a singular Z matrix, which generalizes the corresponding result of . Second, a characterization of convergence for L 1 regular splittings of a singular Z matrix is given, which improve the result of . Third, convergence of weak nonnegative splittings and regular splittings is discussed, and we obtain some necessary and sufficient conditions such that the splittings of a Z matrix converge.
