摘要:

本文考虑三维粘弹性流体流动方程的一个反问题,它源于Kelvin-Voigt流体在有界区域内的运动(一个双曲型问题).该逆问题的目的是从描述为积分过判定条件的测量值同时重建速度和记忆项的核。利用适当空间中的压缩映射原理,得到了Kelvin-Voigt流体反问题解的局部存在唯一性结果.此外,利用类似的论证,还得到了Oseen型方程反问题解的整体存在唯一性结果.

英文摘要:

In this paper, we consider an inverse problem for three dimensional viscoelastic fluid flow equations, which arises from the motion of Kelvin-Voigt fluids in bounded domains (a hyperbolic type problem). This inverse problem aims to reconstruct the velocity and kernel of the memory term simultaneously, from the measurement described as the integral over determination condition. By using the contraction mapping principle in an appropriate space, a local in time existence and uniqueness result for the inverse problem of Kelvin-Voigt fluids are obtained. Furthermore, using similar arguments, a global in time existence and uniqueness results for an inverse problem of Oseen type equations are also achieved.
