In this paper, we present and discuss four types of Mittag-LefflerUlam stability: Mittag-LefflerUlamHyers stability, generalized Mittag- LefflerUlamHyers stability, Mittag-LefflerUlamHyersRassias stability and generalized Mittag-LefflerUlamHyersRassias stability for a fractional evolution equation in Banach spaces. © 2011 Elsevier Ltd.
