M-P inverses and weighted M-P inverses of matrices over a distributive lattice
Limei Zhang · Journal of Shandong University · 2010
M-P inverses and weighted M-P inverses over a distributive lattice are investigated using the binary matrix representation technique(i.e.,lattice matrices are represented by a linear combination of binary matrices).Some equivalent conditions for the existences of these inverses and the structure characters of lattice matrices are given when these inverses exist.
