本文给出了非线性Riemann—Liouville分数阶微分方程和Caputo分数阶微分方程与相应的非线性Volterra积分方程的等价性,并在此基础上建立了分数阶微分方程的比较定理.
In this paper, we show the equivalence between the nonlinear Riemann- Liouville and Caputo fractional differential equations and the Volterra integral equations, respectively. And we also establish the comparison theorems of the fractional differential equations.
