摘要
考虑了一类退化抛物方程全局吸引子的正则性.当非线性项任意阶增长时,通过渐近先验估计方法和投影方法分别得到了这类方程在L^2(Ω),L^p(Ω),L^(2p-2)(Ω)(p≥2)及H_0^(1,a)(Ω)中全局吸引子的存在性.
Asymptotic regularity of the global attractor was proved for a class of degenerate parabolic equations with a polynomially growing nonlinearity of arbitrary order, and the existence of a global attractor in L2(Ω),Lp(Ω),L(2p-2)(Ω)(p≥2) was established by asymptotic a priori estimate and in H01,a(Ω) by the projection method, respectively.
