Singularity formation for compressible Euler equations with time-dependent damping
Ying Sui, Huimin Yu
In this paper, we consider the compressible Euler equations with time-dependent damping \frac{\a}{(1+t)^λ}u in one space dimension. By constructing 'decoupled' Riccati type equatio…

Oscillation of damped second order quasilinear wave equations with mixed arguments
Ying Sui, Huimin Yu
Following the previous work [1], we investigate the impact of damping on the oscillation of smooth solutions to some kind of quasilinear wave equations with Robin and Dirichlet bou…
