In this paper, we investigate the existence of global attractors in Orlicz spaces for reaction–diffusion equations without upper growth restriction on nonlinearity. Firstly, we prove the well-posedness of solutions for the equations in an Orlicz space. Secondly, the existence of -bounded absorbing sets is established. Finally, we obtain the existence of global attractors in any given Orlicz space by proving the asymptotically compactness of generated by the equations.

Orlicz 空间中反应扩散方程的全局吸引子
在本文中,我们研究了 Orlicz 空间中全局吸引子的存在,用于反应扩散方程,而没有非线性增长上限。首先,我们证明了Orlicz空间中方程解的适定性。其次,存在有界吸收集成立。最后,我们通过证明在任何给定的 Orlicz 空间中存在全局吸引子 由方程生成。
