Minkowski空间中半线性wave equations和类时极小曲面的缺陷

Defects in semilinear wave equations and timelike minimal surfaces in Minkowski space

Robert L. Jerrard

摘要:

研究了具有Ginzburg-Landau型非线性项的半线性波动方程,其中$ε>0$是一个小参数.我们证明,对于合适的初始数据,解决方案表现出能量集中集,通过类时Minkowski极小曲面方程的近似演化,只要极小曲面保持光滑。这证明了研究宇宙弦和畴壁的宇宙学家以及应用数学家根据形式渐近和其他启发性论证所作的预言。

英文摘要:

We study semilinear wave equations with Ginzburg-Landau type nonlinearities multiplied by a factor $ε^{-2}$, where $ε>0$ is a small parameter. We prove that for suitable initial data, solutions exhibit energy concentration sets that evolve approximately via the equation for timelike Minkowski minimal surfaces, as long as the minimal surface remains smooth. This gives a proof of predictions made, on the basis of formal asymptotics and other heuristic arguments, by cosmologists studying cosmic strings and domain walls, as well as by applied mathematicians.
