摘要

研究了可积核的非定域Gray-Scott模型在$L_\infty$上的适定性，以及半平凡空间齐次稳态的稳定性。此外，还证明了非局部Gray-Scott系统的解在扩散极限下收敛于经典Gray-Scott系统的解。

A nonlocal Gray-Scott model: Well-posedness and diffusive limit

Well-posedness in $L_\infty$ of the nonlocal Gray-Scott model is studied for integrable kernels, along with the stability of the semi-trivial spatially homogeneous steady state. In addition, it is shown that the solutions to the nonlocal Gray-Scott system converge to those to the classical Gray-Scott system in the diffusive limit.
