摘　　要：In this paper,we study the displacement rank of the Core-EP inverse.Both Sylvester displacement and generalized displacement are discussed.We present upper bounds for the ranks of the displacements of the Core-EP inverse.Numerical experiments are presented to demonstrate the efficiency and accuracy.
