摘要:
We consider the stochastic semilinear degenerate parabolic equation du + [-div(sigma(x)del u) + f(u) + lambda u] dt = gdt + Sigma(m)(j=1) h(j)d omega(j) in a bounded domain O subset of R-N, with the nonlinearity satisfies an arbitrary polynomial growth condition. The random dynamical system generated by the equation is shown to have a random attractor {A(omega)}omega is an element of Omega in D-0(1) (O, sigma) boolean AND L-p(O). The results obtained improve some recent ones for stochastic semilinear degenerate parabolic equations.
