摘要

本文讨论了具有记忆项的伪抛物方程的两个逆源问题,这两个逆源问题在非牛顿流体、过滤、种群动力学、等离子体物理等科学技术领域都有重要的应用。然而,系统中某些附加项的存在通常会在分析和数值分析的数学观点中引起特定的复杂性,尽管它们表征了介质的重要物理特性。所研究的反问题包括在两种积分过定条件下恢复时变源参数。我们在数据上建立了合适条件下强解的存在唯一性和稳定性,并通过创建数值算法和测试实例来探索数值解。

Time-dependent inverse source problems for a pseudoparabolic equation with memory
In this paper, we deal with two inverse source problems for a pseudoparabolic equation with memory term, which in general, have important applications in various fields of science and technology such as non-Newtonian fluids, filtration, population dynamics, plasma physic, et al. However, the presence of certain additional terms in a system usually causes specific complications in mathematical point of view, both in analytical and numerical analysis, although they characterize important physical properties of media. The studied inverse problems consist of recovering a time-dependent source parameter under two types of integral overdetermination conditions. We establish the existence, uniqueness, and stability of strong solutions under suitable conditions on the data and explore numerical solutions by creating numerical algorithms and testing examples.
