Convergence of regular approximations to the spectra of singular fourth-order Sturm–Liouville problems

Abstract

We prove some new results which justify the use of interval truncation as a means of regularising a singular fourth-order Sturm–Liouville problem near a singular endpoint. Of particular interest are the results in the so-called lim-3 case, which has no analogue in second-order singular problems.
