“…The numerical study of (8) in the case when μ = 1/2, m = 4 was first carried out in [12] and [13]. Other studies, including analytical ones, mainly focused on the direct treatment of (9), for those values of the parameters, were carried out in [7], [9], [26], [8], while in [25], general product integration methods for equation (9) with any μ > 0 were analysed; see also [1], where a Nystrom-type method was considered and comparative results were obtained for some particular examples of (8) and (9).…”
