提出了左移和右移分数阶勒让德多项式(SFLPs)两种新的正交函数。从经典的勒让德多项式中直接推广了几个有用的SFLPs公式。导出了SFLPs在Caputo意义上的左、右分数阶微分表达式。作为一个应用,该方法可以有效地求解具有初值问题的分数阶微分方程。
Two new orthogonal functions named the left- and the right-shifted fractional-order Legendre polynomials (SFLPs) are proposed. Several useful formulas for the SFLPs are directly generalized from the classic Legendre polynomials. The left and right fractional differential expressions in Caputo sense of the SFLPs are derived. As an application, it is effective for solving the fractional-order differential equations with the initial value problem by using the SFLP tau method.
