Abstract

In this article, we investigate the coupled Allen-Cahn/Cahn-Hilliard equations with a proliferation term, which can model the growth of cancerous tumors and other biological entities. We focus on establishing the existence, uniqueness, and regularity of solutions, as well as analyzing their asymptotic behavior, with particular attention to the existence of finite-dimensional attractors. The system is considered under Dirichlet boundary conditions, and we introduce assumptions on the proliferation term to ensure dissipativity.

在本文中,我们研究了带有增殖项的 Allen-Cahn/Cahn-Hilliard 耦合方程,它可以模拟癌症肿瘤和其他生物实体的生长。我们的重点是建立解的存在性、唯一性和正则性,并分析其渐近行为,尤其关注有限维吸引子的存在。该系统是在 Dirichlet 边界条件下考虑的,我们引入了增殖项的假设,以确保分散性。

期刊介绍: The Journal of Mathematical Analysis and Applications presents papers that treat mathematical analysis and its numerous applications. The journal emphasizes articles devoted to the mathematical treatment of questions arising in physics, chemistry, biology, and engineering, particularly those that stress analytical aspects and novel problems and their solutions. Papers are sought which employ one or more of the following areas of classical analysis: • Analytic number theory • Functional analysis and operator theory • Real and harmonic analysis • Complex analysis • Numerical analysis • Applied mathematics • Partial differential equations • Dynamical systems • Control and Optimization • Probability • Mathematical biology • Combinatorics • Mathematical physics.
