| heal.abstract | Let the Jacobi matrix B associated with the linear system Aa = b be a weakly cyclic matrix, generated by the cyclic permutation sigma = (sigma(1),sigma(2),...,sigma(p)) as this is defined by Li and Varga. The same authors derived the corresponding functional equation connecting the eigenvalues lambda of the unsymmetric successive overrelaxation (USSOR) iteration matrix T(<omega(omega)over cap>) and the eigenvalues mu of the Jacobi matrix B extending previous results by Gong and Cai. In this paper, the validity of an analogous matrix relationship connecting the operators T(<omega(omega)over cap>) and B is proved. Moreover, the ''equivalence'' of the USSOR method and a certain two-parametric p-step method for the solution of the initial system is established. The tool for the proof of our main result is elementary graph theory. | en |
