Abstract : In this paper, we present the reprentation of all operators $B$ which are Drazin invertible and sharing the spectral projections at 0 with a given Drazin invertible operator $A.$ Meanwhile, some related results for $EP$ operators with closed range are obtained.
Keywords : Drazin inverse, spectral projection, equation of operator
