Moreover, for simplicity it is assumed that [alpha] (t) is a monotone nondecreasing function differentiable with respect to time t.
Here we assume that the functions [f.sub.ij] and [K.sub.ij] are (or bounded by) continuous monotone nondecreasing functions that are not necessarily Lipschitz continuous and they may be unbounded (like power type functions with powers bigger than one).
