“…Special classes of MIRK methods, where the stages are evaluated in equidistant points with integer values 0, 1,... ,s -1 have been studied by the present authors [22]; they have shown that MIRK methods belonging to this subclass are completely equivalent to the previously introduced extended one-step methods [20,13,6,7]. In [10] it has been shown that a one-parameter family of double-stride L-stable methods of fourth-order, obtained by the coupling of three linear multistep methods [8] can also be included within the framework of MIRK methods. P-stable methods for second-order ODEs of the form y"= f(t, y) are constructed either by considering so-called symmetric hybrid methods [3,4,9,[17][18][19] or by using IRKN methods [12].…”
