Abstract
- Some additive results for the Drazin inverses are investigated under conditions weaker than those used in some recent papers on this subject. In particular, a formula is given for the Drazin inverse of a sum of two matrices P , Q ∈ C n × n with P Q i P = 0 for positive integer i = 1 , 2 , ... , n . As an application we give some new representations for the Drazin inverse of a 2 × 2 block matrix. [ABSTRACT FROM AUTHOR]
