abstract = {<p style="text-align: justify;">In this paper, we study numerical approximations of
eigenvalues when using projection method for spectral approximations of
completely continuous operators. We improve the theory depending on the
ascent of $T - \mu$ and provide a new approach for error estimate, which
depends only on the ascent of $T_h - \mu_h$. Applying this estimator to
the integral operator eigenvalue problems, we obtain asymptotically
exact indicators. Numerical experiments are provided to support our
theoretical conclusions.</p>},
