共旋波映射爆破解的构造

A construction of blow up solutions for co-rotational wave maps

Catalin I. Carstea

摘要:

证明了从R^{2+1}到N的波映射问题的共旋转有限时间爆破解的存在性,其中N是具有度量dρ^2+g(ρ)^2 dθ^2的旋转曲面,g是整函数.它们的形式是u(t,r)=Q(λ(t)t)+R(t,r),其中Q是共旋波图方程- u_{tt} + u_{rr} +r^{-1}u_r=r^{-2}g(u)g '(u)的与时间无关的解,λ(t)=t^{-1-ν},ν>1/2是任意的,R是当t变为0时局部能量变为零的项。

英文摘要:

The existence of co-rotational finite time blow up solutions to the wave map problem from R^{2+1} into N, where N is a surface of revolution with metric dρ^2+g(ρ)^2 dθ^2, g an entire function, is proven. These are of the form u(t,r)=Q(λ(t)t)+R(t,r), where Q is a time independent solution of the co-rotational wave map equation -u_{tt}+u_{rr}+r^{-1}u_r=r^{-2}g(u)g'(u), λ(t)=t^{-1-ν}, ν>1/2 is arbitrary, and R is a term whose local energy goes to zero as t goes to 0.
