HIGHLIGHTS
- who: D. Krishnaswamy and G. Sankari from the Department of, Annamalai University, Annamalai Nagar, Tamil Nadu, India have published the Article: Some Results on Core Inverses of Block Matrices Over Skew Fields, in the Journal: (JOURNAL)
SUMMARY
Since rk(B)=rk(BA ), the authors obtain B2=B1 X, B4=B3 X, X ∈ M r×(n-r) (C). Main Results µ A A, where A, B ∈ M n×n (C), rk(B) ≥ rk( A )=r. B 0 (i) the core inverse of M exists if and only if rk( A )=rk(B)=rk( AB)=rk . . .
