 Representation of bounded linear operators with equal spectral projections at zero Commun. Korean Math. Soc. 2010 Vol. 25, No. 4, 547-556 https://doi.org/10.4134/CKMS.2010.25.4.547Printed December 1, 2010 Yun Zhang and Dong-Jun Chen Huaibei Coal Industry Teachers College, Huaibei Coal Industry Teachers College 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 MSC numbers : 47A05, 15A09 Downloads: Full-text PDF
