摘要:

Carrollian流体方程源自相对论流体方程在光速趋于零的极限情况,最近在理论物理学界引起了广泛关注,特别是在渐近对称性和平空间反演领域。本文我们通过在一维空间维度下研究C¹设定,开始对这些方程进行严格的系统分析。我们首先提出熵不变的Carrollian方程的概念,并利用这一概念将Carrollian方程简化为一个2×2的守恒律系统。随后,我们利用Lax的方案,分类讨论在C¹设定下,熵不变的Carrollian方程的全局解是否存在,或在有限时间内破裂。我们的分析假设了Carrollian能量密度的构成关系的类比,其中指数在γ∈(1,3]范围内。

英文摘要:

The Carrollian fluid equations arise from the equations for relativistic fluids in the limit as the speed of light vanishes, and have recently experienced a surge of interest in the theoretical physics community in the context of asymptotic symmetries and flat-space holography. In this paper we initiate the rigorous systematic analysis of these equations by studying them in one space dimension in the $C^1$ setting. We begin by proposing a notion of isentropic Carrollian equations, and use this to reduce the Carrollian equations to a $2 \times 2$ system of conservation laws. Using the scheme of Lax, we then classify when $C^1$ solutions to the isentropic Carrollian equations exist globally, or blow up in finite time. Our analysis assumes a Carrollian analogue of a constitutive relation for the Carrollian energy density, with exponent in the range $γ\in (1,3]$.
