摘要:

本文系统回顾了研究分数方程解定性性质的一系列有效方法。从开创性的扩展方法和积分形式的移动平面方法开始,我们介绍了多种直接方法,包括移动平面法、移动球体法、吹胀和缩放技术、滑动法、正则性提升以及内部和边界正则性估计方法。为阐明这些方法的核心思想,我们通过简单的例子展示它们如何应用于研究解的定性性质。我们还讨论了这些方法各自的优势和局限性。希望本文能成为研究分数方程研究人员的有用参考书。

英文摘要:

In this paper, we systematically review a series of effective methods for studying the qualitative properties of solutions to fractional equations. Beginning with the pioneering extension method and the method of moving planes in integral forms, we introduce a variety of direct methods, including the direct method of moving planes, the method of moving spheres, blow-up and rescaling techniques, the sliding method, regularity lifting, and approaches for interior and boundary regularity estimates. To elucidate the core ideas behind these methods, we employ simple examples that demonstrate how they can be applied to investigate qualitative properties of solutions. We also provide a comparative discussion of their respective strengths and limitations. It is our hope that this paper will serve as a useful handbook for researchers engaged in the study of fractional equations.
