Domains of divergence of the USSOR method applied onp-cyclic matrices

Abstract: Summary. Using a recently derived classical type general functional equation, relating the eigenvalues of a weakly cyclic Jacobi iteration matrix to the eigenvalues of its associated Unsymmetric Successive Overrelaxation (USSOR) iteration matrix, we obtain bounds for the convergence of the USSOR method, when applied to systems with a p-cyclic coefficient matrix.

“…The proof of the second part of the theorem follows immediately upon application of Theorem 3.1 and Corollary 3.1 of [12]. To prove the first part of the theorem, consider ρ(|B A |) ∈ [0, 1) and 0 < σ := ω +ω − ωω < 2, and, recalling Theorems 3.1-3.3 from the previous section and Table 1 from Sect.…”
