摘要：
We develop a new function space and discuss trace operator on the same genealogical spaces. We also prove that the nonlinear boundary value problem with Dirichlet condition: -Delta u = f (vertical bar u vertical bar) sgn u in the given domain, u = 0 on the boundary, possesses only a trivial solution if f obeys the slope condition: alpha' (x) > 2n/n-2 alpha(x)/x, where alpha is the anti-derivative of f with alpha(0) = 0.
