“…; m, with usually k = 1, is also called osculatory or osculating interpolation [25], [26], [31]. The problem corresponding to E = I , with I the (m+1)2(m+1) unit matrix, was studied by Abel [74] and later by Gontcharoff and others [26], [75], [76] and, finally, we mention the two-point interpolation problem studied by Lidstone [26], [76]- [78] for which E is a 2 2(k + 1) matrix with e = 1 for all j even.…”
