本文在小初始扰动假设和无旋条件下,研究了描述热非平衡气体动力学的三维模型解的逐点时空结构,以及在$L^p$框架下对应的背景稳定性。我们的主要工具包括基于无旋条件的修正格林函数、先验能量方法,以及由熵函数和高阶导数构成的乘积的精细衰减估计。
英文摘要
In this paper, both the pointwise space-time structures of the solution for a three-dimensional model describing gas dynamics in thermal non-equilibrium and the corresponding background stabilities within the $L^p$ framework are investigated under the small initial perturbation assumption and the irrotationality condition. Our main tools are the modified Green's function according to the irrotationality condition, a priori energy method and a refined decay estimates of products composed of the entropy function and high-order derivatives.
