abstract = {<p style="text-align: justify;">We discuss the convergence property of the Lanczos method for solving a complex shifted Hermitian linear system $(α I + H)x = f$. By showing the colinear coefficient of two system&#39;s residuals, our convergence analysis reveals that under the condition $Re(α)+ λ _{min}(H)&gt;0$, the method converges faster than that for the real shifted Hermitian linear system $(Re(α) I+H)x=f$. Numerical experiments verify such convergence property.</p>},
