一个GNS不等式和Log-HLS不等式的稳定性及其在临界质量Keller-Segel方程中的应用

Stability for a GNS inequality and the Log-HLS inequality, with application to the critical mass Keller-Segel equation

Eric A. Carlen, Alessio Figalli

摘要:

从Bianchi和Egnell关于2-Sobolev不等式的定量稳定性结果出发,得到了平面上Gagliardo-Nirenberg-Sobolev不等式的几个不同的稳定性结果.然后,利用该不等式与快速扩散方程之间的联系,得到了Log-HLS不等式的定量稳定性.最后,利用这些估计,我们证明了临界质量Keller-Segel系统的一个定量收敛结果。

英文摘要:

Starting from the quantitative stability result of Bianchi and Egnell for the 2-Sobolev inequality, we deduce several different stability results for a Gagliardo-Nirenberg-Sobolev inequality in the plane. Then, exploiting the connection between this inequality and a fast diffusion equation, we get a quantitative stability for the Log-HLS inequality. Finally, using all these estimates, we prove a quantitative convergence result for the critical mass Keller-Segel system.
