摘要: 该文利用重要不等式及能量积分方法首先得到了解的初等的先验估计.然后利用线性半群的有关性质及精细计算得到了解的最大模估计,从而证明了两类三次自催化模型在Dirichlet边界条件下整体解的存在性,并进而证明了第一类模型的最大吸引子的存在性.

关键词: 自催化模型, 整体解, 线性半群, 最大吸引子.

Abstract: The paper first obtains the L2-apriori estimates for the solutions of two kinds of autocatalytic models under Dirichlet boundary conditions, and then, using the properties of linear semigroup and delicate calculations, the estimates of the maximal norms are obtained, therefore, the global existence of the solutions is proved. In the meantime, the existence of the maximal attractor is also given.

Key words: autocatalytic model, global solution, linear semigroup, maximal attractor
