高维 Skyrme 模型的奇点形成

Singularity formation for the higher dimensional Skyrme model

Michael McNulty

AI总结:

本文证明了经典 $(5+1)$ 维 co-rotational Skyrme 模型在有限时间内会发生梯度爆破并形成奇点,且奇点以自相似速率发展并具有由强场极限模型给出的渐近剖面。

摘要:

本文证明了经典 $(5+1)$ 维 co-rotational Skyrme 模型中会形成奇点。Chen、Schörkhuber 和作者最近证明了 $(5+1)$ 维 co-rotational Skyrme 模型的强场极限存在一个显式自相似解,该解在向后光锥内是渐近稳定的。以该极限模型为种子,我们构造了一个初始数据的开集,根据完整模型,其在向后光锥内的演化在有限时间内发生梯度爆破。此外,奇点以自相似速率发展,并具有由强场模型的自相似剖面给出的渐近剖面。

英文摘要:

This paper demonstrates that singularities form in the classical $(5+1)$-dimensional, co-rotational Skyrme model. It was recently proven by Chen, Schörkhuber, and the author that the strong field limit of the $(5+1)$-dimensional, co-rotational Skyrme model admits an explicit self-similar solution which is asymptotically stable within backwards light cones. Seeded by the limiting model, we construct an open set of initial data whose evolution within a backwards light cone, according to the full model, suffers a gradient blowup in finite time. Moreover, the singularity develops at the self-similar rate and possesses an asymptotic profile given by the self-similar profile of the strong field model.
