Hi all,
I've been trying to construct a set of nonlinear PDEs:
P_\nu<u>=0, \qquad \nu = 1, \ldots , l</u>
that has skew-adjoint Frechet derivative, but with no luck. Is there any reason such a system of equations shouldn't exist? Here each P_\nu is an analytic function of the coordinates on <u>\sim\mathrm{pr}^s (x,u)</u>, the s-th jet of (x,u), where x=(x^1, \ldots , x^n) and u = (u^1, \ldots , u^l).
Any help would be much appreciated!
