In this paper,we discuss the soluti ion Cm+l = (Cn) and D = f < 0g where is a real-valued C2-function
in a neighborhood of Dsuch that d 6= 0 and Hz( ; ) has m positive
eigenvalues for any z 2 @D, let f be a continuous (0; q)-form in
such that @f = 0 in D, where l + 1 q l + m, then there exists a
u H
1
2
( D) such that @u = f in D.
