摘要

本文的重点是求解包含子逻辑源的二维Keller-Segel系统。我们证明，即使在强退化的Keller-Segel系统中，子逻辑项的存在也足以防止爆炸现象。我们的证明依赖于几种技术，包括Orlicz空间中的抛物正则性理论、变分参数、插值不等式和Moser迭代法。

Blow-up prevention by sub-logistic sources in Keller-Segel cross diffusion type system

The focus of this paper is on solutions to a two-dimensional Keller-Segel system containing sub-logistic sources. We show that the presence of sub-logistic terms is adequate to prevent blow-up phenomena even in strongly degenerate Keller-Segel systems. Our proof relies on several techniques, including parabolic regularity theory in Orlicz spaces, variational arguments, interpolation inequalities, and the Moser iteration method.

期刊介绍： Centered around dynamics, DCDS-B is an interdisciplinary journal focusing on the interactions between mathematical modeling, analysis and scientific computations. The mission of the Journal is to bridge mathematics and sciences by publishing research papers that augment the fundamental ways we interpret, model and predict scientific phenomena. The Journal covers a broad range of areas including chemical, engineering, physical and life sciences. A more detailed indication is given by the subject interests of the members of the Editorial Board.
