Xingyu Li

摘要:

本文研究了具有外部禁闭势的能斯特-普朗克方程组。主要结果是关于柯西问题解的渐近性态。我们将证明,最佳指数收敛速率的解决方案的唯一固定的解决方案是由周围的自由能的最小值的线性化问题的频谱间隙。关键问题是考虑一个适应的标量积的概念。

英文摘要:

This paper is devoted to the Nernst-Planck system of equations with an external potential of confinement. The main result is concerned with the asymptotic behaviour of the solution of the Cauchy problem. We will prove that the optimal exponential rate of convergence of the solution to the unique stationary solution is determined by the spectral gap of the linearized problem around the minimizer of the free energy. The key issue is to consider an adapted notion of scalar product.
