Difference schemes of high-order accuracy for problems with jacobi-type degeneracy

An exact and a truncated difference schemes are constructed for eigenvalue boundary-value problems for a differential equation with the same degeneracy as the Jacobi polynomial equation. The truncated scheme of rank m is shown to be accurate to (m +1)-st order.Kiev University. Translated from Vychislitel'naya i Prikladnaya Matematika, No. 67, pp. 3–15, 1989.
