Maximum principles for fractional differential equations derived from Mittag-Leffler functions. (English) Zbl 1202.34019

Nieto, Juan J.

Appl. Math. Lett. 23, No. 10, 1248-1251 (2010).

Summary: We present two new maximum principles for a linear fractional differential equation with initial or periodic boundary conditions. Some properties of the classical Mittag-Leffler functions are crucial in our arguments. These comparison results allow us to study the corresponding nonlinear fractional differential equations and to obtain approximate solutions.
