abstract = {<p style="text-align: justify;">We use extrapolation acceleration technique to speed up the preconditioned
square block matrix splitting iteration method for two-by-two block linear systems. It
is shown that for relaxation parameter $ω$ = 4/3, the convergence factor of the iteration method under consideration is 1/3. This yields the robustness and efficiency of
the method. Numerical examples confirm the theoretical results and demonstrate the
effectiveness of the approach developed.</p>},
