On sums of conjugate secondary range hermitian matrices

S. Krishnamoorthy, B.K.N. Muthugobal


Necessary and Sufficient conditions for the sum of conjugate      s-EP (con-s-EP) matrices to be Con-s-EP are discussed.  As an application it is shown that sum and sum of parallel summable Con-s-EP matrices are  Con-s-EP.
