Electronic journal of differential equations, Tome 2007 (2007)
Let

$\displaylines{ J_{a}u=\sum_{| \alpha | }(-1)^{| \alpha | }D^{\alpha }g_{\alpha }(x,D^{\alpha }u) \quad\hbox{in }\Omega , \cr D^{\alpha }u=0\hbox{ on }\partial \Omega , | \alpha | \leq m-1, }$

where

$ \| u\| _{m,A}=\| \sqrt{T[u,u]}\| _{(A)}, $
