Query: Equiconvergence for perturbed Jacobi polynomial expansions   We show asymptotic expansions of the eigenfunctions of certain perturbations
of the Jacobi operator in a bounded interval, deducing equiconvergence results
between expansions with respect to the associated orthonormal basis and
expansions with respect to the cosine basis. Several results for pointwise
convergence then follow.
