Convergence for Semilinear Degenerate Parabolic Equations in Several Space Dimensions

We show that any global nonnegative and bounded solution to the degenerate parabolic problemut-Δum+f(u)=0 qquad {\rm on} quad Ώ⊂ RN,u|{∂Ώ}=0converges to a single stationary state as time goes to infinity. Here m>0, f is a restriction of a real analytic function defined on a sector containing the half-line [0, ∞), and f(u1/m) is a continuously differentiable function of u.
