Local energy decay of solutions to the linearized compressible viscoelastic system around motionless state in an exterior domain (2505.23169v1)
Published 29 May 2025 in math.AP
Abstract: We study the large time behavior of solutions to the system of equations describing motion of compressible viscoelastic fluids. We focus on the linearized system around a motionless state in a three-dimensional exterior domain and derive the local energy decay estimate of its solution to give the diffusion wave phenomena caused by sound wave viscous diffusion and elastic shear wave.
