本文对一维空间有界区间上一般双组分反应-扩散系统的首次动态转变提供了全面刻画。通过严格处理两个组分之间非线性相互作用所带来的困难，本研究显著扩展了以往关于反应-扩散系统动态转变研究的范围，这些先前研究主要集中于单方程情形。分析采用中心流形约化方法，并置于标准动态转变理论分类框架下进行。本研究的一个关键贡献在于，非线性项被处理为涉及未知量$u$和$v$的任意幂次。此外，理论框架通过对一个代表性且简化系统的分析得到补充。由于这一推广，一大类基本反应-扩散系统的动力学可被系统分类。
英文摘要
This work provides a comprehensive characterization of the first dynamic transition of a general two-component reaction-diffusion system on a bounded interval in one spatial dimension. By rigorously addressing the difficulties arising from the non-linear interactions between the two components, this study significantly extends the scope of previous studies on dynamic transitions of reaction-diffusion systems, which focused on single-equation cases. The analysis is conducted by employing center manifold reduction within the standard classification of dynamic transition theory. A key contribution of this study is that the nonlinear terms are treated to involve arbitrary powers of the unknowns $u$ and $v$. Furthermore, the theoretical framework is complemented by the analysis of a representative and simplified system. As a result of this generalization, the dynamics of a broad class of fundamental reaction-diffusion systems can be systematically classified.
