Abstract

In this paper, we are interested in the global well-posedness of the strong solutions to the Cauchy problem on the compressible magnetohydrodynamics system with Hall effect. Moreover, we establish the convergence rates of the above solutions trending towards the constant equilibrium \(({\bar{\rho }},0,\bar{\textbf{B}})\), provided that the initial perturbation belonging to \(H^3({\mathbb {R}}^3) \cap B_{2, \infty }^{-s}({\mathbb {R}}^3)\) for \(s \in (0,\frac{3}{2}]\) is sufficiently small.

可压缩霍尔-磁流体动力学系统的最佳时间衰减率

本文研究了具有霍尔效应的可压缩磁流体动力学系统的Cauchy问题强解的全局适定性。此外，我们还建立了上述解趋向于常平衡的收敛速率 \(({\bar{\rho }},0,\bar{\textbf{B}})\)，则初始摄动属于 \(H^3({\mathbb {R}}^3) \cap B_{2, \infty }^{-s}({\mathbb {R}}^3)\) 为了 \(s \in (0,\frac{3}{2}]\) 足够小。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
