We shall show that condition (4), in conjunction with all the conditions of the theorem except (2), is not sufficient. Whether it is necessary is apparently still open. However, results in [4] show that Wong's conjecture is true in the case where f(x) is also nondecreasing (or bracketed between two nondecreasing functions that satisfy (4)). An analysis of the two theorems proved in [1] shows that a counterexample to his conjecture (call the solution x(t)) will have to satisfy
