在仅考虑交叉吸收效应的放松假设下具有质量控制的反应扩散系统的整体存在性

Global existence in reaction-diffusion systems with mass control under relaxed assumptions merely referring to cross-absorptive effects

Johannes Lankeit, Michael Winkler

摘要:

本文引入了反应扩散方程组解的广义概念,并证明了其整体解的存在性。除了正则性、准正性和质量控制之外,对反应函数的唯一限制是特殊的,因为它仅仅控制交叉吸收项的增长。结果涵盖非线性扩散,不依赖于熵估计。

英文摘要:

We introduce a generalized concept of solutions for reaction-diffusion systems and prove their global existence. The only restriction on the reaction function beyond regularity, quasipositivity and mass control is special in that it merely controls the growth of cross-absorptive terms. The result covers nonlinear diffusion and does not rely on an entropy estimate.
