A method which can be used to solve the initial value problem for certain classes of nonlinear Partial Differential Equations. The method reduces the initial value problem to a linear Integral Equation in which time appears only implicitly. However, the solutions and various of their derivatives must approach zero as (Infeld and Rowlands 1990).
