一般分数松弛方程的估计及其在源反问题中的应用

Estimates for a general fractional relaxation equation and application to an inverse source problem

Emilia Bazhlekova

摘要:

本文考虑了一般分数阶松弛方程,并引入了A. Kochubei(Integr.当量ag Oper Theory 71(2011),583-600)。该方程推广了单项、多项和分布阶分数阶松弛方程。详细研究了基本解和脉冲响应解。属性,如解析性和从属身份的建立和就业的证明的上界和下界。所得结果推广了Mittag-Leffler函数的一些已知性质。作为估计的应用,得到了有界区域上一般时间分数阶扩散方程源反问题解的唯一性和条件稳定性.

英文摘要:

A general fractional relaxation equation is considered with a convolutional derivative in time introduced by A. Kochubei (Integr. Equ. Oper. Theory 71 (2011), 583-600). This equation generalizes the single-term, multi-term and distributed-order fractional relaxation equations. The fundamental and the impulse-response solutions are studied in detail. Properties such as analyticity and subordination identities are established and employed in the proof of an upper and a lower bound. The obtained results extend some known properties of the Mittag-Leffler functions. As an application of the estimates, uniqueness and conditional stability are established for an inverse source problem for the general time-fractional diffusion equation on a bounded domain.
