一类线性分数阶微分方程的平稳守恒律

Stationarity-conservation laws for certain linear fractional differential equations

M. Klimek

摘要:

在Laplace卷积定义的函数代数中研究了分数阶Riemann-Liouville导数的Leibniz定则。该代数和导出的莱布尼茨规则被用于构造线性分数阶微分方程的定常守恒流的显式形式。详细讨论了1+1维分数扩散和d+1维分数扩散的例子。将所得结果推广到混合分数阶微分系统和混合序列分数阶微分系统,得到了它们的平稳性守恒律。推导出的电流用于建设固定的非本地电荷。

英文摘要:

The Leibniz rule for fractional Riemann-Liouville derivative is studied in algebra of functions defined by Laplace convolution. This algebra and the derived Leibniz rule are used in construction of explicit form of stationary-conserved currents for linear fractional differential equations. The examples of the fractional diffusion in 1+1 and the fractional diffusion in d+1 dimensions are discussed in detail. The results are generalized to the mixed fractional-differential and mixed sequential fractional-differential systems for which the stationarity-conservation laws are obtained. The derived currents are used in construction of stationary nonlocal charges.
