Abstract:The quantitative stability for sharp inequalities in analysis and geometry is a fascinating subject that has attracted many researchers for decades. Since the seminar works of Brezis and Lieb (1985), many results have appeared dealing with the properties of the Sobolev inequalities, their variants, harmonic maps, etc. In contrast, the quantitative stability for the solutions to the Euler-Lagrange equations induced by sharp inequalities has been less understood. Nonetheless, it was completely analyzed in a Hilbertian Sobolev setting recently, thanks to the contributions of Ciraolo et al. (2018 IMRN), Figalli and Glaudo (2020 ARMA), and Deng et al. (2024 DUKE). In this talk, I will introduce my recent works on quantitative stability, collaborated with S. Kim (Hanyang U.) and J. Wei (CUHK) for the fractional Lane-Emden equation of all possible orders and the Yamabe problem.
