Let E be n-dimensional (n≧2) real vector space with a nondegenerate symmetric scalar product (.|.):E × ER1 with an arbitrary signature (p, np). Let us consider a second order partial differential equation (P.D.E.) of the form:

where φ is a given function of two variables, v is an unknown function (defined on an open subset 0 ⊂E), |∇ν|2: =(∇ν|∇ν) is the square of the gradient ∇ν of the function ν and ∇2, denotes the Laplace-Beltrami operator.
