R. R. Ashurov, R. T. Zunnunov

AI总结:

本文研究混合型方程中确定分数阶导数阶数的反问题,通过附加条件实现了对次扩散和波动方程中未知分数阶参数的唯一确定。

摘要:

本文考虑了混合型方程中确定分数阶阶数的反问题。在区域的一部分,所考虑的方程是具有Gerasimov-Caputo意义下阶数为0<a<1的分数阶导数的次扩散方程,在另一部分是阶数为1<b<2的分数阶导数的波动方程。方程的椭圆部分是一个二阶算子,在N维区域D中考虑。假设参数a和b未知,找到了提供所需参数明确确定的附加条件。

英文摘要:

In this paper the inverse problem of determining the fractional orders in mixed-type equations is considered. In one part of the domain the considered equation is the subdiffusion equation with a fractional derivative in the sense of Gerasimov-Caputo of the order 0<a<1 , and in the other part - a wave equation with a fractional derivative of the order 1<b<2 . The elliptic part of the equation is a second-order operator, considered in a N - dimensional domain D. Assuming the parameters a and b to be unknown, additional conditions are found that provide an unambiguous determination of the required parameters.
