Abstract

The large time behavior of the solutions to a multi-dimensional viscous conservation law is considered in this paper. It is shown that the solution time-asymptotically tends to the planar rarefaction wave if the initial perturbations are multi-dimensional periodic. The time-decay rate is also obtained. Moreover, a Gagliardo–Nirenberg type inequality is established in the domain $\mathbb{R} \times \mathbb{T}^{n-1} (n \geq 2)$, where $\mathbb{T}^{n-1}$ is the $n-1$-dimensional torus.

Keywords
