abstract = {<p style="text-align: justify;">In this paper, we consider weakly regular Sturm-Liouville eigenproblems with unbounded potential at both endpoints of the domain. We propose a Galerkin spectral matrix
method for its solution and we study the error in the eigenvalue approximations it provides. The
result of the convergence analysis is then used to derive a low-cost and very effective formula for
the computation of corrected numerical eigenvalues. Finally, we present and discuss the results of
several numerical experiments which confirm the validity of the approach.</p>},
