具有Dirac相互作用的双幂反应扩散方程平衡解的稳定性

Stability of equilibrium solutions of a double power reaction diffusion equation with a Dirac interaction

César Adolfo Hernández Melo, Edgar Yesid Mayorga Lancheros

摘要:

本文给出了一类一维非线性定域反应扩散方程平衡解的不稳定性的详细信息。除此之外,我们提供了明确的公式的平衡解决方案,通过扰动法,我们计算的线性算子的正特征值的确切数目的稳定性问题,这使我们能够计算的非稳定流形的尺寸。

英文摘要:

In this paper we provide detailed information about the instability of equilibrium solutions of a nonlinear family of localized reaction-difussion equations in dimensione one. Beyond we provide explicit formulas to the equilibrium solutions, via perturbation method and we calculate the exact number of positive eigenvalues of the linear operator associated to the stability problem, which allow us to compute the dimension of the unstable manifold.
