J. Apraiz, A. Doubova, E. Fernández-Cara, M. Yamamoto

摘要:

本文研究了Burgers方程及其相关的非线性系统(包括热效应和/或变密度)的一维反问题。在这些问题中,目标是从解的一些适当的边界观测值中找到空间区间的大小。根据初始和边界数据的性质,我们证明了唯一性和非唯一性结果。此外,我们还解决了一些这些反问题的数值和计算近似的区间大小。

英文摘要:

In this article we deal with one-dimensional inverse problems concerning the Burgers equation and some related nonlinear systems (involving heat effects and/or variable density). In these problems, the goal is to find the size of the spatial interval from some appropriate boundary observations of the solution. Depending on the properties of the initial and boundary data, we prove uniqueness and non-uniqueness results. In addition, we also solve some of these inverse problems numerically and compute approximations of the interval sizes.
