略$L^2$ -超临界广义KdV方程的稳定自相似爆破动力学

Stable self-similar blow-up dynamics for slightly $L^2$-supercritical generalized KdV equations

Yang Lan

摘要:

本文考虑具有非线性项$5<p<5+\varepsilon$和$0<\varepsilon\ll 1$的弱$L^2$ -超临界gKdV方程组$\partial_t u+(u_{xx}+u|u|^{p-1})_x=0$.我们将证明能量空间$H^1$中具有自相似爆破速率的爆破动力学的存在性和稳定性,并给出爆破时刻附近奇点形成的具体描述。

英文摘要:

In this paper we consider the slightly $L^2$-supercritical gKdV equations $\partial_t u+(u_{xx}+u|u|^{p-1})_x=0$, with the nonlinearity $5<p<5+\varepsilon$ and $0<\varepsilon\ll 1$ . We will prove the existence and stability of a blow-up dynamic with self-similar blow-up rate in the energy space $H^1$ and give a specific description of the formation of the singularity near the blow-up time.
