Behavior of Solutions Nonlinear Reaction-Diffusion PDE's Relation to Dynamics of Propagation of Cancer

Kamal N. Soltanov

摘要:

本文提出了一个新的描述肿瘤扩散动力学的非线性反应扩散偏微分方程数学模型。在这里,混合问题的建议PDE的调查,并通过应用所获得的结果得出结论的动态癌症的传播。这些问题具有非局部非线性与可变指数,并具有特殊的性质:这些可以是保持耗散的所有时间或成为非耗散后,有限的时间。在这里,证明了问题在尚未耗散和变为非耗散时的可解性和解的行为。它表明,如果所研究的过程变得非耗散可以有各种状态,例如,一个无限数量的不同的不稳定的解决方案与不同的速度,此外,他们的传播可以成为混沌。这些解决方案的行为进行了详细的分析,并解释了如何时空混沌可以出现。对该数学模型的研究可以解释癌症传播的动力学,在此作为每个病例的结论提供。

英文摘要:

In this paper, we propose a new mathematical model nonlinear reaction-diffusion PDE's describing the dynamics of propagation of cancer. Here the mixed problem for the proposed PDE's is investigated and by applying obtained results conclusions on the dynamics of propagation of cancer are drawn. These problems have nonlocal nonlinearity with variable exponents and possess special properties: these can be to remain either dissipative all time or become non-dissipative after a finite time. Here the solvability and behavior of solutions both when problems are yet dissipative and when become nondissipative are proved. It is shown that if the studied process gets become nondissipative can have various states, e.g. an infinite number of different unstable solutions with varying speeds, in addition, their propagation can become chaotic. The behavior of these solutions is analyzed in detail and it is explained how space-time chaos can arise. Investigation of this mathematics model allows explaining the dynamics of propagation of cancer, which are provided here as conclusions for each case.
