摘要

摘要本文证明了具有有界$$\dot{H} ^1$$ H˙1范数的能量临界非线性热方程解的一个局域冒泡结果。该证明使用了gsamim的配置文件分解(ESAIM Control Optim)的组合。Calc. Var. 3: 213 - 233,1998)，在Duyckaerts, Kenig和Merle的开创性工作的精神集中密实技术(Geom。函数。《论文集》，2012年第22期:639-698页)，以及在贾和柯尼格的作品精神中进行的一场病毒式辩论(美国)。[j] .数学学报，39(1):1521-1603,2017)，以推断气泡之间的颈部区域误差的消失。该论证紧密地基于作者最近与Jendrej (arXiv:2210.14963, 2022)在二维等变调和映射热流上证明的一个类似引理。

Localized Sequential Bubbling for the Radial Energy Critical Semilinear Heat Equation

Abstract In this expository note, we prove a localized bubbling result for solutions of the energy critical nonlinear heat equation with bounded $$\dot{H} ^1$$ H ˙ 1 norm. The proof uses a combination of Gérard’s profile decomposition (ESAIM Control Optim. Calc. Var. 3 : 213–233, 1998), concentration compactness techniques in the spirit of Duyckaerts, Kenig, and Merle’s seminal work (Geom. Funct. Anal. 22 : 639–698, 2012), and a virial argument in the spirit of Jia and Kenig’s work (Amer. J. Math. 139 : 1521–1603, 2017) to deduce the vanishing of the error in the neck regions between the bubbles. The argument is based closely on an analogous lemma proved in the author’s recent work with Jendrej (arXiv:2210.14963, 2022) on the equivariant harmonic map heat flow in dimension two.
