“…In the context of solving just problems of type (1.4), there are still important LMMs for which no γ > 0 exists such that (1.12), (1.9) imply monotonicity, cf. [34] (p.283), [19], [20]. Moreover, the conditions on γ, given in the literature and relevant to (1.11), were obtained in the context of general (nonlinear) problems (1.1), and they are far from simple.…”
