$\mathbb R^{2+1}$波图对一般目标的散射

Scattering of Wave Maps from $\mathbb R^{2+1}$ to general targets

Joules Nahas

摘要:

我们表明,光滑,径向对称波映射$U$从$\mathbb R^{2+1}$到一个紧凑的目标流形$N$,其中$\partial_r U$和$\partial_t U$有紧凑的支持任何固定的时间,分散。结果将遵循Christodoulou和Tahvildar-Zadeh以及Struwe的工作,在证明对于$λ' \in (0,1)$,能量不集中在集合$$K_{5/8T,7/8T}^{λ'} = {(x,t) \in \mathbb R^{2+1} | {5pt} |x| \leq λ' t, t \in [(5/8)T,(7/8)T]}.$$中之后

英文摘要:

We show that smooth, radially symmetric wave maps $U$ from $\mathbb R^{2+1}$ to a compact target manifold $N$, where $\partial_r U$ and $\partial_t U$ have compact support for any fixed time, scatter. The result will follow from the work of Christodoulou and Tahvildar-Zadeh, and Struwe, upon proving that for $λ' \in (0,1)$, energy does not concentrate in the set $$K_{5/8T,7/8T}^{λ'} = {(x,t) \in \mathbb R^{2+1} | {5pt} |x| \leq λ' t, t \in [(5/8)T,(7/8)T]}.$$
