二次梯度非线性遗传流体中的Jordan-Moore-Gibson-Thompson wave equation

On the Jordan-Moore-Gibson-Thompson wave equation in hereditary fluids with quadratic gradient nonlinearity

Vanja Nikolić, Belkacem Said-Houari

摘要:

在$\mathbb{R}^n$中证明了带记忆的三阶含时Jordan-More-Gibson-Thompson声波方程的整体可解性,其中$n \geq 3$ .该波动方程模拟了松弛遗传流体中的超声波传播,并结合了局部和累积非线性效应。全局可解性的证明是基于在时间上一致的高阶能量界的序列,并且是在指数衰减的记忆核和足够小且规则的初始数据的假设下导出的。

英文摘要:

We prove global solvability of the third-order in time Jordan-More-Gibson-Thompson acoustic wave equation with memory in $\mathbb{R}^n$, where $n \geq 3$. This wave equation models ultrasonic propagation in relaxing hereditary fluids and incorporates both local and cumulative nonlinear effects. The proof of global solvability is based on a sequence of high-order energy bounds that are uniform in time, and derived under the assumption of an exponentially decaying memory kernel and sufficiently small and regular initial data.
