Tianling Jin, Jingang Xiong

AI总结:

本文研究有界光滑区域中带Dirichlet零边界的Sobolev临界快扩散方程非负解的熄灭行为,在双泡能量阈值假设下证明了解按相对误差一致收敛至稳态或爆破泡的二分性。

摘要:

本文研究带Dirichlet零边界条件的有界光滑区域中,Sobolev临界快扩散方程非负解的熄灭行为。在初始数据满足双泡能量阈值假设下,我们证明了二分性:所有解按相对误差一致收敛到稳态,或是爆破泡。

英文摘要:

In this paper, we investigate the extinction behavior of nonnegative solutions to the Sobolev critical fast diffusion equation in bounded smooth domains with the Dirichlet zero boundary condition. Under the two-bubble energy threshold assumption on the initial data, we prove the dichotomy that every solution converges uniformly, in terms of relative error, to either a steady state or a blowing-up bubble.
