关于全局吸引子的正则性

On the regularity of global attractors

Monica Conti, Vittorino Pata

摘要:

本文重点讨论了一种新的方法,在不要求时间一致估计的情况下,证明了耗散动力系统的全局吸引子在更正则空间中的有界性。作为抽象结果的应用,考虑了具有临界非线性项的强阻尼波动方程$$u_{tt}-Δu_t-Δu+ϕ(u)=f$$生成的半群,证明了其吸引子具有最优正则性.

英文摘要:

This note is focused on a novel technique in order to establish the boundedness in more regular spaces for global attractors of dissipative dynamical systems, without appealing to uniform-in-time estimates. As an application of the abstract result, the semigroup generated by the strongly damped wave equation $$u_{tt}-Δu_t-Δu+ϕ(u)=f$$ with critical nonlinearity is considered, whose attractor is shown to possess the optimal regularity.
