一类具有一般奇异非线性项的抛物型方程组的渐近性和熄灭性

Asymptotic and Quenching Behavior for a family of Parabolic System with General Singular Nonlinearities

Qi Wang, Yanyan Zhang

摘要:

本文研究一类具有一般奇异非线性项的抛物型系统,它是MEMS系统的推广。在一定程度上,给出了根据参数和初始数据的全局存在性和熄灭性的分类。此外,还得到了收敛速度。指出与单一的MEMS方程相比,本文的研究在获得系统的收敛速度方面引入了新的思想和技术。实际上,由于线性化椭圆方程组第一特征值的变分刻画的缺乏,求单方程收敛速度的方法在这里不能完全适用。

英文摘要:

This study is concerned with a family of parabolic system with general singular nonlinearities, which is a generalization of MEMS system. To some extent, the classification of global existence and quenching according to parameters and initial data is given. Moreover, the convergence rate is also obtained. We point out that compared to single MEMS equation, new ideas and techniques are introduced in obtaining the convergence rate for system in our study. In fact, due to the lack of variational characterization for the first eigenvalue of the linearized elliptic system, the methods in obtaining convergence rate for single equation cannot work completely here.
