The Given

Given an equation of the form z = ϕ ( x 1 , x 2 , ..... x n+m , a 1 , a 2 ,. . . . a n ), we obtain by differentiation with respect to each of the n + m independent variables x 1 , x 2 , ..... x n+m , and elimination of the n arbitrary constant a 1 , a 2 ,. . . . a n a system of m +1 non-linear partial differential equations of the first order. Of this system the given equation may be said to be "complete primitive.”

Given an equation of the form z = ϕ ( x 1 , x 2 , . . . x n+r , a 1 , a 2 ,... a r , a + r + 1 ), we obtain by differentiation with respect to each of the n + r variables n + r equations, together with the original equation n + r + 1 equations, from which, eliminating the r + 1 constants, we have a system of n nonlinear partial differential equations. Conversely, given a system of n non-linear partial differential equations with n + r independent variables, if there exists an equation
