一次测量唯一确定分数阶扩散(波)方程中的几个系数

Unique determination of several coefficients in a fractional diffusion(-wave) equation by a single measurement

Yavar Kian, Zhiyuan Li, Yikan Liu, Masahiro Yamamoto

摘要:

我们考虑的反问题,确定不同类型的信息的扩散过程中,所描述的普通或分数扩散方程上的有界域,如密度的介质或速度场与移动量从一个单一的边界测量。这个属性将与一些一般类的时间无关的系数,我们恢复从一个单一的诺依曼边界测量,在某些部分的边界上,我们的扩散方程的解决方案与适当的边界输入,位于某些部分的边界。

英文摘要:

We consider the inverse problem of determining different type of information about a diffusion process, described by ordinary or fractional diffusion equations stated on a bounded domain, like the density of the medium or the velocity field associated with the moving quantities from a single boundary measurement. This properties will be associated with some general class of time independent coefficients that we recover from a single Neumann boundary measurement, on some parts of the boundary, of the solution of our diffusion equation with a suitable boundary input, located on some parts of the boundary.
