具有I型记忆的粘弹性阻尼wave equation的渐近分布和奇异极限

Asymptotic profiles and singular limits for the viscoelastic damped wave equation with memory of type I

Wenhui Chen

摘要:

本文研究一类具记忆项的粘弹性阻尼波动方程的Cauchy问题。通过WKB分析和傅里叶分析,我们解释了记忆对具有加权$L^1$初始数据的模型的耗散结构和解的渐近分布的影响。进一步,考虑到标准能量和解本身,建立了具有记忆的Moore-Gibson-Thompson方程与具有记忆的粘弹性阻尼波动方程之间的奇异极限关系.

英文摘要:

In this paper, we are interested in the Cauchy problem for the viscoelastic damped wave equation with memory of type I. By applying WKB analysis and Fourier analysis, we explain the memory's influence on dissipative structures and asymptotic profiles of solutions to the model with weighted $L^1$ initial data. Furthermore, concerning standard energy and the solution itself, we establish singular limit relations between the Moore-Gibson-Thompson equation with memory and the viscoelastic damped wave equation with memory.
