MATHEMATICS A general type of second- order partial differential equation which includes the wave equation and has the form
where the Aij , Bi , C, and F are suitably differentiable real functions of x1, x2, . . ., xn , and there exists at each point (x1, x2, . . ., xn ) a real linear transformation on the xi which reduces the quadratic form
to a sum of n squares not all of the same sign.
