In this paper, we study the Riemann problem for a \(2 \times 2\) nonstrictly hyperbolic system with linear damping. We introduce the special time-dependent viscosity to obtain approximate solutions. Therefore, we solve the Riemann problem (1.1)–(1.2) by limiting viscosity approach.

具有线性阻尼的2×2 $ 2 \ times 2 $双曲系统的Riemann问题

在本文中,我们研究具有线性阻尼的\(2 \ times 2 \)严格双曲系统的Riemann问题。我们介绍了特殊的随时间变化的粘度以获得近似解。因此,我们通过限制粘度方法解决了黎曼问题(1.1)–(1.2)。
