the usual assumption of monotonicity, we establish some results on the theory
of hyperbolic differential inequalities which enable us to produce a majorising
interval function for the solution of the hyperbolic initial value problem.
Using this function, a variation of parameters formula and interval iterative
technique, the existence of solution to the problem is established.
