Weighted moore-penrose, Drazin, and group inverses of the Kronecker product A circle times operator B, and some applications Original Research Article

The representations for the weighted Moore-Penrose inverse, the Drazin inverse, and the group inverse of the Kronecker product A circle times operator B of the two matrices A and B are given, and by using these results, the determinant forms for projectors AA+MN, A+MNA, AdA, and AgA are deduced.
