摘要
本文使用 Galerkin 方法作为转换技术,将移位 Vieta-Lucas 多项式的分数阶导数扩展到涉及非局部边界条件的广义分数积分微分方程,得到了 N - \delta + 1 个线性代数方程系统,其中 \lambda i, i = 0, ., N 个未知数,再加上 \delta 非局部边界条件,我们得到了 (N + 1)- 个线性方程。我们从文献中选取了一些问题来检验该方案的准确性和有效性。从结果表和图中可以看出,与有多项式精确解的问题相对应的近似解给出了闭式解,而与现有结果相比,有非多项式精确解的问题给出了更好的精度。
Approximate analytical solution of fractional-order generalized integro-differential equations via fractional derivative of shifted Vieta-Lucas polynomial
In this paper, we extend fractional-order derivative for the shifted Vieta-Lucas polynomial to generalized-fractional integro-differential equations involving non-local boundary conditions using Galerkin method as transformation technique and obtained N - \delta + 1 system of linear algebraic equations with \lambda i, i = 0, . . . , N unknowns, together with \delta non-local boundary conditions, we obtained (N + 1)- linear equations. The accuracy and effectiveness of the scheme was tested on some selected problems from the literature. Judging from the table of results and figures, we observed that the approximate solution corresponding to the problem that has exact solution in polynomial form gives a closed form solution while problem with non-polynomial exact solution gives better accuracy compared to the existing results.
